However, Centaurs and TNOs are unlikely to have significantly dispersed young asteroid families in the main belt, although they can have perturbed some old asteroid families. Current main belt asteroids that originated as Centaurs or trans-Neptunian objects may lie in the outer belt with short lifetime of less than 4 million years, most likely ...
Most highly inclined known main-belt asteroid from August 17, 1998, to October 19, 1998 MPC (88043) 2000 UE 110: 51.998° October 29, 2000 First main-belt asteroid discovered and numbered to have an inclination greater than 50°. MPC (138925) 2001 AU 43: 72.132° January 4, 2001 A Mars-crosser and near-Earth object. MPC (127546) 2002 XU 93: 77 ...
The asteroid and comet belts orbit the Sun from the inner rocky planets into outer parts of the Solar System, interstellar space. [ 16 ] [ 17 ] [ 18 ] An astronomical unit , or AU, is the distance from Earth to the Sun, which is approximately 150 billion meters (93 million miles). [ 19 ]

42 of the largest objects in the asteroid belt. If possible, asteroids should always be placed into one of the numerous sub-categories, in line with the category information given in the minor-planet catalog. Used sources: Small Body Data Ferret (Nesvorný) and AstDys (Milani and Knežević).
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 AU and its absolute magnitude is 22 or brighter. [2]
Various asteroid classes are colour coded: 'generic' main-belt asteroids are white. Inside the main belt, there are the Atens (red), Apollos (green), and Amors (blue). Outside the main belt are the Hildas (blue) and the Trojans (green). All object position vectors have been normalized to the length of the object's semi-major axis. The Kirkwood ...
At a diameter of 964 km, Ceres is the largest object in the main asteroid belt and comprises about one-third of the belt's total mass. Ceres possesses sufficient gravity to form a rounded, ellipsoid shape, suggesting that it is close to being in hydrostatic equilibrium [ 6 ] —one of the conditions for defining a dwarf planet according to the ...
