A body that orbits the Sun and is not a planet, dwarf planet, or satellite. The category was defined at the 2006 conference of the IAU (International Astronomical Union). It includes: the comets; the bodies traditionally called asteroids, except for the largest, Ceres; the asteroids orbiting beyond Jupiter, called Centaurs; the Trojans, asteroid-like bodies that accompany the planets; the Trans-Neptunian Objects, except for the largest, such as Pluto and Eris; and meteoroids.

SSSBs are irregular in shape: they are not massive enough to be pulled into a sphere by their own gravity.
