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.

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 ...

List Of Earth-crossing Minor Planets
An Earth-crosser is a near-Earth asteroid whose orbit crosses that of Earth as observed from the ecliptic pole of Earth's orbit. The known numbered Earth-crossers are listed here. Those Earth-crossers whose semi-major axes are smaller than Earth's are Aten asteroids; the remaining ones are Apollo asteroids. ''(See also the Amor asteroids.)'' An asteroid with an Earth-crossing orbit is not necessarily in danger of colliding with Earth. The orbit of an Earth-crossing asteroid may not even intersect with that of Earth. This apparent contradiction arises because many asteroids have highly inclined orbits, so although they may have a perihelion less than that of Earth, their paths can never cross. An asteroid for which there is some possibility of a collision with Earth at a future date and which is above a certain size is classified as a potentially hazardous asteroid (PHA). Specifically, an asteroid is a PHA if its Earth minimum orbital intersection distance (MOID) is <0.05 [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of Mercury-crossing Minor Planets
A Mercury crosser is an asteroid whose orbit crosses that of Mercury. The Mercury crossers proper have aphelia outside Mercury's (0.4667 AU) and perihelia inside Mercury's (0.3075 AU), whereas those listed here as outer grazers have perihelia within Mercury's aphelion but not within its perihelion. All have semi-major axes larger than Mercury's, and hence there are no known inner grazers. List Mercury crossers proper have aphelia outside Mercury's (0.4667 AU) and perihelia inside Mercury's (0.3075 AU). , 362 Mercury crossers were known.

List Of Centaurs (small Solar System Bodies)
The following is a list of centaurs, a group of non-resonant small Solar System bodies whose orbit around the Sun lie typically between the orbits of Jupiter and Neptune (5 to 30 AU). Centaurs are minor planets with characteristics of comets, and often classified as such. The dynamical group is formed due to Neptune's eroding effect on the Kuiper belt by means of gravitational scattering, sending objects inward to become centaurs, or outward to become scattered-disc objects, or removing them from the Solar System entirely. Centaurs themselves have unstable orbits with short lifetimes, transitioning from the inactive population of Kuiper belt objects to the active group of Jupiter-family comets within a few million years. List The list of centaurs is compiled from MPC's MPCORB data file based on criteria defined by the JPL-SBDB, and completed with objects from the ''List of Known Trans-Neptunian Objects'' and ''The Deep Ecliptic Survey Object Classifications''. by William Joh ...

83982 Crantor
83982 Crantor (), '' prov. designation'': , is a centaur in a 1:1 resonance with Uranus, approximately in diameter. It was discovered on 12 April 2002, by astronomers of the Near-Earth Asteroid Tracking at the Palomar Observatory in California, United States. This minor planet was named for Crantor from Greek mythology. Orbit and classification ''Crantor'' orbits the Sun at a distance of 14.0–24.9 AU once every 85 years and 10 months (31,342 days). Its orbit has a semi-major axis of 19.5 AU, a moderate eccentricity of 0.28, and an inclination of 13 ° with respect to the ecliptic. The minor planet was first observed on a precovery taken by the Sloan Digital Sky Survey on 19 March 2001. One night later, the body's observation arc begins with an observation by the Air Force Maui Optical Station (AMOS) at Haleakala Observatory on the island of Hawaii, more than a year prior to its official discovery observation by NEAT.

65489 Ceto
65489 Ceto, as a binary also (65489) Ceto/Phorcys, is a binary trans-Neptunian object (TNO) discovered on March 22, 2003, by Chad A. Trujillo and Michael Brown at Palomar. It is named after the sea goddess Ceto from Greek mythology. It came to perihelion in 1989. Physical characteristics 65489 Ceto is an example of a close binary TNO system in which the components are of similar size. Combined observations with the infrared Spitzer Space Telescope and the Hubble Space Telescope allow the diameter of Ceto itself to be estimated at and the diameter of Phorcys at , assuming equal albedo for both components. The binary nature of Ceto enables direct calculation of the system mass, allowing estimation of the masses of the components and providing additional constraints on their composition. The estimated density of Ceto is , significantly less than that of the large TNOs (Haumea: 3.0 g/cm3, Eris: 2.26, Pluto: 2.03, Charon: 1.65) but significantly more than that of smaller TN ...
