Small Solar System body (SSSB) is an object in the Solar System that is neither a planet, nor a dwarf planet, nor a natural satellite. The term was first defined in 2006 by the International Astronomical Union (IAU).
All other objects, except satellites, orbiting the Sun shall be referred to collectively as “Small Solar System Bodies” … These currently include most of the Solar System asteroids, most Trans-Neptunian Objects (TNOs), comets, and other small bodies.
