Small solar system body
The English used in this article or section may not be easy for everybody to understand. (July 2012)
- All other objects 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.
Therefore, it refers to these objects that can be further grouped based on their orbit or what they are made of:
- all known minor planets that are not dwarf planets, i.e.:
- all comets;
- It is not yet clear whether there will be a lower bound on the group of small solar system bodies, or if it will encompass all material down to the level of meteoroids.
Some of the larger "small solar system bodies" may be reclassified in future as dwarf planets, pending further examination to determine whether or not they are in hydrostatic equilibrium (nearly-round shape).
