Most occultations are visible only in the Southern Hemisphere, because the star is at the northern edge of the lunar occultation zone. Rarely, it may be occulted as far north as southern California.
The deeper of the two eclipses is called the primary regardless of which star is being occulted, and if a shallow second eclipse also occurs it is called the secondary eclipse. The size of the brightness drops depends on the relative brightness of the two stars, the proportion of the occulted star that is hidden, and the surface brightness (i.e. effective temperature) of the stars. Typically the occultation of the hotter star causes the primary eclipse.

The planetoid is mobile, and powered by the mysterious "quasar-force". Millions of years ago, it was moved to the Sol System, where it settled into orbit behind Mars; it is permanently occulted by the planet and not visible from Earth. In time, Snikeria became overpopulated. So, many Sniks slowly immigrated to Mars, and developed a subterranean system of paths and supply lines.
Magellan was powered by two square solar arrays, each measuring 2.5 meters across. Together, the arrays supplied 1,200 watts of power at the beginning of the mission. However, over the course of the mission the solar arrays gradually degraded due to frequent, extreme temperature changes. To power the spacecraft while occulted from the Sun, twin 30 amp-hour, 26-cell, nickel-cadmium batteries were included.

In May 2018, Himalia occulted a star, allowing for precise measurements of its size. The occultation was observed from the US state of Georgia. From the occultation, Himalia was given a size estimate of , in agreement with earlier ground-based estimates.
Differential bending of light was measured to be consistent with general relativity. Regulus was occulted by the asteroid 163 Erigone in the early morning of March 20, 2014. The center of the shadow path passed through New York and eastern Ontario, but no one is known to have seen it, due to cloud cover. The International Occultation Timing Association recorded no observations at all.
Atmospheric radio occultation relies on the detection of a change in a radio signal as it passes through a planet's atmosphere, i.e. as it is occulted by the atmosphere. When electromagnetic radiation passes through the atmosphere, it is refracted (or bent). The magnitude of the refraction depends on the gradient of refractivity normal to the path, which in turn depends on the density gradient.

Twice during the orbital cycles of Jupiter and Saturn, the equatorial (and satellite) planes of those planets are aligned with Earth's orbital plane, resulting in a series of mutual occultations and eclipses between the moons of these giant planets. The terms eclipse, occultation, and transit are also used to describe these events. A satellite of Jupiter (for example) may be eclipsed (i.e. made dimmer because it moves into Jupiter's shadow), occulted (i.e.
Based upon its spectrum, 47 Aglaja is listed as a C-type asteroid under the Tholen classification taxonomy, indicating a carbonaceous composition. The SMASS classification system rates it as a rare B-type asteroid. There is a broad absorption feature at 1 μm that is associated with the presence of magnetite and is what gives the asteroid its blue tint. On 16 September 1984, the star SAO 146599 was occulted by 47 Aglaja.

Hind on June 24, 1852, and named after Melpomenē, the Muse of tragedy in Greek mythology. It is classified as an S-type asteroid and is composed of silicates and metals. Melpomene occulted the star SAO 114159 on December 11, 1978. A possible Melpomenean satellite with a diameter at least 37 km was detected.
The tiny change in brightness of the system during these occultations will require at least a medium-aperture professional telescope for detection. Hiʻiaka last occulted Haumea in 1999, a few years before discovery, and will not do so again for some 130 years. However, in a situation unique among regular satellites, Namaka's orbit is being greatly torqued by Hiʻiaka, which preserved the viewing angle of Namaka–Haumea transits for several more years.

Since it is near the ecliptic, it can be occulted by the Moon and, very rarely, by planets.
Earth and Moon avoidance keeps bright light out of the FGSs, and keeps scattered light from entering the instruments. If the FGSs are turned off, however, the Moon and Earth can be observed. Earth observations were used very early in the program to generate flat-fields for the WFPC1 instrument. There is a so-called continuous viewing zone (CVZ), at roughly 90° to the plane of Hubble's orbit, in which targets are not occulted for long periods.
On May 17, 2005, this asteroid occulted a faint star (magnitude 8.5) and the event was observed and timed in a number of locations within the U.S. and Mexico. As a result, a silhouette profile was produced, yielding a roughly oval cross- section with dimensions of 160 × 135 km (± 1 km).D.W. Dunham, "Upcoming Asteroid Occultations", Sky & Telescope, June, 2006, p. 63. The mass of the asteroid can be estimated based upon the mutually perturbing effects of other bodies, yielding an estimate of .

It is positioned near the ecliptic and so it can be occulted by the Moon.
Aside from the Mahdi's precise genealogy, Sunnis accept many of the same hadiths which Shias accept about the predictions regarding the Mahdi's emergence, his acts, and his universal Caliphate. Sunnis also have many hadiths about Mahdi which are in their Hadith collections. Muhammad ibn Al-Hasan and At-Tayyib Abu'l-Qasim ibn Al-Mansur are descendants of the Islamic Nabi (Prophet) Muhammad who are considered by different groups of Shi'ites (respectively Twelvers and Tayyibi Isma'ili-Musta'li-Isma'ilis) to be Occulted Imams and Mahdis.
This divot is hypothesized to be due to either the collisional evolution of the population, or to be due to the population having formed with no objects below this size, with the smaller objects being fragments of the original objects. As of December 2009, the smallest Kuiper belt object detected is 980 m across. It is too dim (magnitude 35) to be seen by Hubble directly, but it was detected by Hubble star tracking system when it occulted a star.
It is 0.05 degree north of the ecliptic, so can be occulted by the moon and planets. This is a G-type giant star with a stellar classification of G6/8III. With an estimated age of 282 million years, it is an evolved, thin disk star that is currently on the red horizontal branch. The interferometry-measured angular diameter of this star is , which, at its estimated distance, equates to a physical radius of nearly 16 times the radius of the Sun.
Values for stellar radii vary significantly in different sources and for different observation methods. The angular diameters of many stars can be measured directly using stellar interferometry. Other methods can use lunar occultations or from eclipsing binaries, which can be used to test indirect methods of finding stellar radii. Only a few useful supergiant stars can be occulted by the Moon, including Antares A (Alpha Scorpii A). Examples of eclipsing binaries are Epsilon Aurigae (Almaaz), VV Cephei, and V766 Centauri (HR 5171).
Rho Leonis is classified as a runaway star, which means it has a peculiar velocity of at least 30 km s−1 relative to the surrounding stars. It has radial velocity of away from the Sun and a proper motion that is carrying it about 1.56 Astronomical Units per year, equivalent to 7 km s−1, in a transverse direction. The star is situated about above the galactic plane. Rho Leo is 0.15 degree north of the ecliptic, so it can be occulted by the moon.
In 2008, it was considered to be a dwarf planet based on its lightcurve amplitude and the assumption that it was larger than in diameter. Because is a member of the Haumea family, it is assumed to have an albedo of around 0.7, which would result in a diameter of about . occulted a relatively bright apparent magnitude 13.1 star in the constellation of Andromeda on 9 October 2009. This event was visible from Australia, possibly New Zealand, and the southern United States and Mexico.
The faint tertiary star, Eta Virginis B, orbits the inner group in a wider orbit over a period of 13.1 years. Eta Virginis is 1.97 degrees north of the ecliptic, so it can be occulted by the Moon and (rarely) by planets. On October 12, 272 BC the ancient Greek astronomer Timocharis observed a conjunction of the star with Venus. The last occultation by a planet took place on September 27, 1843, also by Venus, which will occult it again on November 19, 2445.
The precursor to the filar micrometer was the micrometer eyepiece, invented by William Gascoigne. Earlier measures of angular distances relied on inserting into the eyepiece a thin metal sheet cut in the shape of a narrow, isosceles triangle. The sheet was pushed into the eyepiece until the two adjacent edges of the metal sheet simultaneously occulted the two objects of interest. By carefully measuring the position where the objects were extinguished and knowing the focal length of the objective lens, the angular distance could be calculated.
Theta Cancri, Latinized from θ Cancri, is a multiple star system in the zodiac constellation of Cancer. It is visible to the naked eye as a dim point of light with an apparent visual magnitude of +5.32. The system is located at a distance of approximately 450 light years away from the Sun, based on parallax, and is drifting further away with a radial velocity of +44 km/s. Since it is near the ecliptic, it can be occulted by the Moon and, very rarely, by planets.
The coronagraph has recently been adapted to the challenging task of finding planets around nearby stars. While stellar and solar coronagraphs are similar in concept, they are quite different in practice because the object to be occulted differs by a factor of a million in linear apparent size. (The Sun has an apparent size of about 1900 arcseconds, while a typical nearby star might have an apparent size of 0.0005 and 0.002 arcseconds.) Earth-like exoplanet detection requires contrast. To achieve such contrast requires extreme optothermal stability.
Alpha Librae (α Librae, abbreviated Alpha Lib, α Lib) is a double star and, despite its 'alpha' designation, it is the second-brightest star system (or star) in the constellation of Libra. The two components are designated α¹ Librae and α² Librae. The system bore the traditional name of Zubenelgenubi , though the International Astronomical Union now regards that name as only applying to α² Librae. Alpha² Librae is 0.33 degrees north of the ecliptic so it can be occulted by the Moon and (very rarely) by planets.
Beta Virginis (β Virginis, abbreviated Beta Vir, β Vir), formally named Zavijava , is (despite its designation 'beta') the fifth-brightest star in the constellation of Virgo. Larger and more massive than the Sun, it is comparatively metal-rich (that is, it has a higher preponderance of elements heavier than helium). It is 0.69 degrees north of the ecliptic, so it can be occulted by the Moon and (rarely) by planets. The next planetary occultation of Zavijava will take place on 11 August 2069, by Venus.
Diomedes was the first Jupiter trojan that was successfully observed during an asteroid occultation, when it occulted the star HIP 014402A over Japan on 7 November 1997. The silhouette was elongated with a major and minor occultation axis of kilometers (poor fit). The ellipsoid dimensions of kilometers – corresponding to a mean-diameter of 132.5 kilometers, equivalent to the volume of a sphere – were estimated using follow-up photometry at Ondřejov Observatory and Mitaka Observatory that determined the body's rotational phase at the exact time of the occultation event.
This relation extended to stars which lay away from the ecliptic and could not be occulted by the Moon, as well as to Cepheid variables, yielding their distances. The relation between angular diameter and V-R colour index is termed the Barnes- Evans Relation, which is calibrated by using direct diameter observations of Cepheid variables. Using these relations the distance is calculated to delta Cephei, and compared with an independent distance derived from trigonometric parallax measurements by the Hubble Space Telescope - the two measurements agree to within a few percent.
Sigma Sagittarii has a spectrum matching a stellar classification of B2.5 V, which indicates this is a B-type main-sequence star. Its total luminosity is 3300 times that of the Sun while it has a surface temperature of 18,890 K. X-ray emission has been detected from this star, which has an estimated X-ray luminosity of . It has a 10th magnitude optical companion located 5.2 arcminutes away. It is 3.45 degrees south of the ecliptic, so it can be occulted by the Moon and rarely by planets.
Radio science is commonly used to determine the gravity field of a moon or planet by observing Doppler shift. This requires a highly stable oscillator on the spacecraft, or more commonly a "2-way coherent" transponder that phase locks the transmitted signal frequency to a rational multiple of a received uplink signal that usually also carries spacecraft commands. Another common radio science observation is performed as a spacecraft is occulted by a planetary body. As the spacecraft moves behind the planet, its radio signals cuts through successively deeper layers of the planetary atmosphere.
To maximize the number of sources occulted by the Moon, a highly eccentric orbit (e ~ 0.93) with a 90.6 hr period and an inclination of 73° was chosen. The initial apogee was 191,000 km and perigee 350 km. To be outside the Earth's radiation belts, the scientific instruments were operated above ~50,000 km, giving up to ~76 hr per 90 hr orbit. There was no need for any onboard data storage as Exosat was visible from the ground station at Villafranca, Spain for practically the entire time the scientific instruments were operated.
It is claimed to be the heaviest among planet-harboring stars with reliable initial masses although the star HD 13189 is potentially more massive. Given its large mass, this star, though presently of spectral type K0 III, was formerly of spectral type A that has now evolved off the main sequence into the giant phase. It is regarded as a red clump giant; that is, a core-helium burning star. Since Epsilon Tauri lies near the plane of the ecliptic, it is sometimes occulted by the Moon and (very rarely) by planets.
The word "transit" refers to cases where the nearer object appears smaller than the more distant object. Cases where the nearer object appears larger and completely hides the more distant object are known as occultations. In astronomy, planetary transits and occultations occur when a planet passes in front of another object, as seen by an observer. The occulted object may be a distant star, but in rare cases it may be another planet, in which case the event is called a mutual planetary occultation or mutual planetary transit, depending on the relative apparent diameters of the objects.
This method was developed in the 1820s by the German mathematician and astronomer, Friedrich Wilhelm Bessel, and later improved by William Chauvenet. The basic concept is that Besselian elements describe the movement of the shadow cast by the occulting body – for solar eclipses this is the shadow of the Moon – on a specifically chosen plane, called the fundamental plane. This is the geocentric, normal plane of the shadow axis. In other words, it is the plane through the Earth's center that is perpendicular to the line through the centers of the occulting and the occulted bodies.
For 7 March 2017, a stellar occultation by Orcus had been predicted to take place in the Americas and over the Pacific Ocean. Observations were made at five sites in North and South America, and two solid body chords have been observed. Using speckle imaging, the occulted star was revealed to be a close double star, and a reconstruction of the orbits of Orcus and Vanth showed that both chords were from Vanth (occulting either of the two stars) rather than Orcus. A non-detection at a nearby site placed a constraint of () on the diameter of Vanth.
Size comparison of Pollux (left) and The Sun (right) At an apparent visual magnitude of 1.14, Pollux is the brightest star in its constellation, even brighter than its neighbor Castor (α Geminorum). Pollux is 6.7 degrees north of the ecliptic, too far north to be occulted by the moon and planets, but in the distant future it will be close enough. Parallax measurements by the Hipparcos astrometry satellite place Pollux at a distance of about from the Sun. The star is larger than the Sun, with about two times its mass and almost nine times its radius.
One rather complex task that falls to STScI is scheduling observations for the telescope. Hubble is in a low-Earth orbit to enable servicing missions, but this means most astronomical targets are occulted by the Earth for slightly less than half of each orbit. Observations cannot take place when the telescope passes through the South Atlantic Anomaly due to elevated radiation levels, and there are also sizable exclusion zones around the Sun (precluding observations of Mercury), Moon and Earth. The solar avoidance angle is about 50°, to keep sunlight from illuminating any part of the OTA.
Path of occultation from New York to Ontario In the early morning hours of March 20, 2014, Erigone occulted the first-magnitude star Regulus as first predicted by A. Vitagliano in 2004. This would have been a rare case of an occultation of a very bright star visible from a highly populated area, since the shadow path moved across New York state and Ontario, including all five boroughs of New York City. Observers in the shadow path would have seen the star wink out for as long as 14 seconds. However, heavy clouds and rain blocked the view for most if not all people on the shadow path.
The presence of carbon dioxide on the surface suggests that Titania may have a tenuous seasonal atmosphere of CO2, much like that of the Jovian moon Callisto. Other gases, like nitrogen or methane, are unlikely to be present, because Titania's weak gravity could not prevent them from escaping into space. At the maximum temperature attainable during Titania's summer solstice (89 K), the vapor pressure of carbon dioxide is about 300 μPa (3 nbar). On September 8, 2001, Titania occulted a bright star (HIP 106829) with a visible magnitude of 7.2; this was an opportunity to both refine Titania's diameter and ephemeris, and to detect any extant atmosphere.
The estimated age is 1.6 billion years. It has an apparent visual magnitude of +3.53, allowing it to be seen with the naked eye. It is 0.18 degree south of the ecliptic so it is occasionally occulted by the Moon and, rarely, by a planet; and is eclipsed by the sun from about 10-12 July.In the Sky Earth astronomy reference utility showing the ecliptic and relevant date as at J2000 - present Thus the star can be viewed the whole night, crossing the sky, in mid-January. The last occultation by a planet was by Saturn on June 30, 1857, and the next will be by Venus on August 12, 2420.
Delta Capricorni (δ Capricorni, abbreviated Del Cap or δ Cap) is a multiple star system about 39 light-years away in the constellation of Capricornus (the Sea Goat). The primary star in the system is a white giant and the combined light of its members makes it the brightest star in the constellation. The system consists of an eclipsing binary, Delta Capricorni A, and two companion stars, B and C. A's two components are themselves designated Delta Capricorni Aa (formally named Deneb Algedi , the traditional name of the system) and Ab. Delta Capricorni is 2.6 degrees south of the ecliptic and can be occulted by the Moon, and (rarely) by planets.
Jupiter being occulted by the moon, 16 June 2005, in Nelson, New Zealand N.P. Wieth-Knudsen Observatory is next to Tisvilde Hegn, two hours away from Copenhagen, Denmark, at Margot Nyholms vej 19, 3220 Tisvildeleje, on the outskirts of a small residential area in Tisvilde, away from artificial light generated by larger cities. It was constructed in 1959 by Dr. Niels Palle Wieth-Knudsen (1909–1993), who used the observatory until his death. His biggest contribution to astronomy was the observation of lunar occultations, during which the moon passes in front of stars, the data from which is then used in the accurate determination of the lunar position. This became important during the moon landings during the sixties.
Because the Moon's orbit around Earth is inclined by about 5.145° (5° 9') to the orbit of Earth around the Sun, eclipses do not occur at every full and new moon. For an eclipse to occur, the Moon must be near the intersection of the two orbital planes. The periodicity and recurrence of eclipses of the Sun by the Moon, and of the Moon by Earth, is described by the saros, which has a period of approximately 18 years. Because the Moon continuously blocks the view of a half-degree-wide circular area of the sky, the related phenomenon of occultation occurs when a bright star or planet passes behind the Moon and is occulted: hidden from view.
151 The more radical experimenters, including Sion's student Jacques Hérold, rejected tame modernism altogether, turning to Surrealism; Petre Răileanu, "Mitul transparenței", in Observator Cultural, Nr. 115, May 2002 but young neo-traditionalists such as Elena Popea found in it a source of inspiration. Aurel D. Broșteanu, "Cronica plastică. Elena Popea", in Gândirea, Nr. 10-11/1930, p.403 (digitized by the Babeș-Bolyai University Transsylvanica Online Library) Retrospectively, philosopher and curator Erwin Kessler finds in Sion the exponent of "a reactionary Romanian modernism": artistic nationalism, coming at a time when all modern Romanian art was divided along ethnic lines ("the ethnic component of classical modernism played an important role, one that should be explained, not occulted").
Paul Oldfield wrote in the English music newspaper, Melody Maker in 1985: "Theirs [RēR Quarterly] is the pursuit of unimaginable, packed in artwork of giddy luminescence." In a review of Vol. 4 No. 1 at AllMusic, François Couture wrote that the music on the CD covers a broad range of styles, and that "[i]t takes wide ears and a solid stomach to switch from Cornelius Cardew's sweet- and-sour orchestral music to N.O.R.M.A.'s street band exuberance". He praised the tracks by Thinking Plague, Tom Nunn, Al Margolis and N.O.R.M.A., and said the album is "important" because pieces by Les Sales Combles, Diledadafish and Koongoortoog are the only recorded works left by these "occulted projects".
HST Saturn portrait from 20 June 2019 From time to time, Saturn is occulted by the Moon (that is, the Moon covers up Saturn in the sky). As with all the planets in the Solar System, occultations of Saturn occur in "seasons". Saturnian occultations will take place monthly for about a 12-month period, followed by about a five-year period in which no such activity is registered. The Moon's orbit is inclined by several degrees relative to Saturn's, so occultations will only occur when Saturn is near one of the points in the sky where the two planes intersect (both the length of Saturn's year and the 18.6-Earth year nodal precession period of the Moon's orbit influence the periodicity).
Hyades Aldebaran is one of the easiest stars to find in the night sky, partly due to its brightness and partly due to being near one of the more noticeable asterisms in the sky. Following the three stars of Orion's belt in the opposite direction to Sirius, the first bright star encountered is Aldebaran. The star is, by chance, in the line of sight between the Earth and the Hyades, so it has the appearance of being the brightest member of the open cluster, but the cluster that forms the bull's-head-shaped asterism is more than twice as far away, at about 150 light years. Aldebaran is 5.47 degrees south of the ecliptic and so can be occulted by the Moon.
Combining these observations with thermal measurements taken in 2000, the sizes of the components of the system were estimated at 106 km and 98 km, with an equivalent whole-system diameter of 145 km, refined by later measurements from the Keck Observatory to approximately 122 km and 112 km for each partner, and a co-orbital period of hours ( days). On 21 October 2013, both bodies occulted a magnitude 8.8 star as observed by a team of 41 observers stationed across the USA. Observation data put the orbital distance of 664.6 km, and give a size for the slightly larger component, which retains the name Patroclus with overall volume equivalent to a 113 km sphere, with the smaller component now named Menoetius with a volume equivalent to a 104 km diameter sphere.
With a measured mean temperature of ~ , the upper limit of Quaoar's atmospheric pressure is expected to be in the range of a few microbars. Due to Quaoar's small size and mass, the possibility of Quaoar having an atmosphere of nitrogen and carbon monoxide has been ruled out, since the gases would escape from Quaoar. The possibility of a methane atmosphere, with the upper limit being less than 1 microbar, was considered until 2013, when Quaoar occulted a 15.8 magnitude star and revealed no sign of a substantial atmosphere, placing an upper limit to at least 20 nanobars, under the assumption that Quaoar's mean temperature is and that its atmosphere consists of mostly methane. The upper limit of atmosphere pressure was tightened to 10 nanobars after another stellar occultation in 2019.
Zeta Piscium (ζ Piscium, abbreviated Zet Psc, ζ Psc) is a quintuple star system in the zodiac constellation of Pisces. Based upon parallax measurements obtained during the Hipparcos mission, it is located roughly distant from the Sun. The system consists of a binary star (Zeta Piscium A) and a triple star system (BC), the latter consisting of a spectroscopic binary (B) and a single star (C). A's two components are themselves designated Zeta Piscium Aa (officially named Revati ) and Ab; B's two components as Ba and Bb. As the star system is 0.21° south of the ecliptic, it can be eclipsed (occulted) by the moon, when close to or at one of its two nodes of its orbit; and is eclipsed by the sun from about 8-10 April.
South America is visible. The minimum angular separation would be less than 1′, and occasionally the Moon would be seen to transit in front of or pass behind (be occulted by) the Earth. The former case would correspond to a lunar occultation of Mars as seen from Earth, and because the Moon's albedo is considerably less than that of the Earth, a dip in overall brightness would occur, although this would be too small to be noticeable by casual naked eye observers because the size of the Moon is much smaller than that of the Earth and it would cover only a small fraction of the Earth's disk. Mars Global Surveyor imaged the Earth and Moon on May 8, 2003 13:00 UTC, very close to maximum angular elongation from the Sun and at a distance of 0.930 AU from Mars.
The target field had to avoid known bright sources of visible light (such as foreground stars), and infrared, ultraviolet and X-ray emissions, to facilitate later studies at many wavelengths of the objects in the deep field, and also needed to be in a region with a low background infrared 'cirrus', the diffuse, wispy infrared emission believed to be caused by warm dust grains in cool clouds of hydrogen gas (H I regions). These criteria restricted the field of potential target areas. It was decided that the target should be in Hubble's 'continuous viewing zones' (CVZs)—the areas of sky which are not occulted by the Earth or the moon during Hubble's orbit. The working group decided to concentrate on the northern CVZ, so that northern-hemisphere telescopes such as the Keck telescopes, the Kitt Peak National Observatory telescopes and the Very Large Array (VLA) could conduct follow-up observations.
Jamkaran in Iran, supposed site of a historical appearance of Muhammad al-Mahdi In the tradition of Twelver Shia Islam, the twelfth and final Imam, Muhammad al-Mahdi, who is also considered by Twelver Shia to be the prophesied redeemer of Islam known as the Mahdi, went into ghaybah ("occultation") in 873. However, this belief has long been criticized by Sunni scholars who "often speculate that the twelfth Imam never existed, but was a myth designed to keep the Shia cause alive."The Routledge Handbook of Religion and Security, by Chris Seiple, Dennis R. Hoover, Pauletta Otis, 2012, page 60 Meanwhile, western scholars have also cast doubt upon the existence of an occulted Imam. According to Robert Gleave, the occultation of the 12th Imam "became subsequent orthodox doctrine" after none of the competing theories that sought to explain the succession to a childless 11th Imam "seemed satisfactory".
Jupiter (the bright object in the upper right) a few minutes before being occulted by the Moon on June 16, 2005 An occultation is an astronomical event where a celestial object appears completely hidden by another, closer body (with a greater angular diameter) due to the passage of the closer object directly between the more distant object and the observer. Due to the large apparent size of the Moon, lunar occultations are quite common and when a bright celestial object is involved, the result is an event that can be easily observed using the naked eye. The Moon almost constantly occults faint stars as it orbits the Earth but because even a young Moon appears immensely brighter than these stars, these events are difficult to observe using amateur telescopes. However, the Moon does frequently occult brighter stars and even planets due to its close proximity to the ecliptic.
