Minor Planet
According to the International Astronomical Union (IAU), a minor planet is an astronomical object in direct orbit around the Sun that is exclusively classified as neither a planet nor a comet. Before 2006, the IAU officially used the term ''minor planet'', but that year's meeting reclassified minor planets and comets into dwarf planets and small Solar System bodies (SSSBs).Press release, IAU 2006 General Assembly: Result of the IAU Resolution votes International Astronomical Union, August 24, 2006.

(65407) 2002 RP120
, provisional designation ', is a trans-Neptunian object and damocloid from the outer Solar System. Its orbit is retrograde and comet-like, and has a high eccentricity. It was discovered on 4 September 2002 by astronomers with the LONEOS survey at Anderson Mesa Station, Arizona, in the United States. The unusual object measures approximately in diameter and is likely elongated in shape. It is a slow rotator and potentially a tumbler as well. The object was probably ejected from the ecliptic by Neptune. Orbit and classification ' is a member of the damocloids, with a retrograde orbit and a negative TJupiter of −0.8340. It is also a trans-Neptunian object, as its orbit has a semi-major axis larger than that of Neptune (30.1 AU). The Minor Planet Center lists it as a critical object, centaur, and (other) unusual minor planet due to an orbital eccentricity of more than 0.5. It orbits the Sun at a distance of 2.5–105 AU once every 396 years (semi-major axis of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
(60608) 2000 EE173
6 (six) is the natural number following 5 and preceding 7. It is a composite number and the smallest perfect number. In mathematics Six is the smallest positive integer which is neither a square number nor a prime number; it is the second smallest composite number, behind 4; its proper divisors are , and . Since 6 equals the sum of its proper divisors, it is a perfect number; 6 is the smallest of the perfect numbers. It is also the smallest Granville number, or \mathcal-perfect number. As a perfect number: *6 is related to the Mersenne prime 3, since . (The next perfect number is 28.) *6 is the only even perfect number that is not the sum of successive odd cubes. *6 is the root of the 6-aliquot tree, and is itself the aliquot sum of only one other number; the square number, . Six is the only number that is both the sum and the product of three consecutive positive numbers. Unrelated to 6's being a perfect number, a Golomb ruler of length 6 is a "perfect ruler". Six is a con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
(55638) 2002 VE95
, '' prov. designation'': , is a trans-Neptunian object from the outermost region of the Solar System. It was discovered on 14 November 2002, by astronomers with the Near-Earth Asteroid Tracking program at the Palomar Observatory in California, United States. This resonant trans-Neptunian object is a member of the plutino population, locked in a 2:3 resonance with Neptune. The object is likely of primordial origin with a heterogeneous surface and a notably reddish color ( RR) attributed to the presence of methanol and tholins. It has a poorly defined rotation period of 6.8 hours and measures approximately in diameter, too small to be a dwarf planet candidate. , it has not yet been named. Orbit and classification ' belongs to the plutino population, named after its largest member, Pluto. Plutinos are resonant trans-Neptunian objects, that are locked in a stable 2:3 mean-motion resonance with Neptune, orbiting the Sun twice for every three orbits Neptune does. They form ...

55576 Amycus
55576 Amycus is a centaur discovered on 8 April 2002 by the NEAT at Palomar. The minor planet was named for Amycus, a male centaur in Greek mythology. It came to perihelion in February 2003. Data from the Spitzer Space Telescope gave a diameter of . A low probability asteroid occultation of star UCAC2 17967364 with an apparent magnitude of +13.8 was possible on 11 February 2009. Another such event involving a star with an apparent magnitude of +12.9 occurred on 10 April 2014 at about 10:46 Universal Time, visible for observers in the southwest US and western Mexico. Near 3:4 resonance of Uranus Amycus (2002 GB10) lies within 0.009 AU of the 3:4 resonance of Uranus and is estimated to have a long orbital half-life of about 11.1 Myr.

52975 Cyllarus
52975 Cyllarus , '' prov. designation'': , is a very red centaur, approximately in diameter, orbiting the Sun in the outer Solar System. It was discovered on 12 October 1998, by American astronomer Nichole Danzl at the Kitt Peak National Observatory near Sells, Arizona, in the United States. It was later named after the mythological creature Cyllarus. Orbit and classification ''Cyllarus'' orbits the Sun in the outer main-belt at a distance of 16.3–36.0 AU once every 133 years and 5 months (48,739 days). Its orbit has an eccentricity of 0.38 and an inclination of 13 ° with respect to the ecliptic. ''Cyllarus'' came to perihelion in September 1989. The body's observation arc begins with its official discovery observation at Kitt Peak, as no precoveries were taken, and no prior identifications were made. Naming This minor planet was named for the Cyllarus, a centaur of Greek mythology. The official was published by the Minor Planet Center on 14 June 2003 (). A sy ...

is an eccentric trans-Neptunian object with a centaur-like orbit from the outer Solar System, approximately 150 kilometers in diameter. It was discovered on 21 July 1999, by astronomers John Kavelaars, Brett Gladman, Matthew Holman and Jean-Marc Petit at Mauna Kea Observatories, Hawaii, United States. Orbit and classification orbits the Sun at a distance of 17.6–46.6 AU once every 181 years and 9 months (66,375 days).

42355 Typhon
42355 Typhon (; '' prov. designation'': ), is a scattered disc object that was discovered on February 5, 2002, by the NEAT program. It measures 162±7 km in diameter, and is named after Typhon, a monster in Greek mythology.

38628 Huya
38628 Huya ( ), provisional designation , is a binary trans-Neptunian object located in the Kuiper belt, a region of icy objects orbiting beyond Neptune in the outer Solar System. Huya is classified as a plutino, a dynamical class of trans-Neptunian objects with orbits in a 3:2 orbital resonance with Neptune. It was discovered by the Quasar Equatorial Survey Team and was identified by Venezuelan astronomer Ignacio Ferrín in March 2000. It is named after Juyá, the mythological rain god of the Wayuu people native to South America. Huya's surface is moderately red in color due to the presence of complex organic compounds on its surface. Water ice has been suspected to be also present on its surface, although water ice has not been directly detected on Huya. Huya is considered as a mid-sized trans-Neptunian object, with an estimated diameter of about . Huya is considered to be a possible dwarf planet, though its relatively small size and dark surface may imply that it never co ...
