An asteroid is an irregularly shaped rocky body orbiting the Sun that does not qualify as a planet or a dwarf planet under the International Astronomical Union’s (IAU) definitions of those terms introduced in 2006. In contrast to planets and dwarf planets, asteroids do not have sufficient mass for their self-gravity to overcome rigid body forces and assume a hydrostatic equilibrium (nearly round) shape. In contrast to comets, asteroids are inert bodies that do not display a coma of gas and dust. Very small objects with a size of less than about 10 m are normally referred to as meteoroids.
