2060 Chiron spectroscopy is consistent with that used to explain Chiron's long-term brightness variations. The preferred pole of Chiron's rings is, in ecliptic coordinates, "λ" = , "β" = . The rings' width, separation, and optical depths are nearly identical to those of Chariklo's rings, indicating that the same type of structure is responsible for both. Moreover, both their rings are within their respective Roche limits. 2060 Chiron 2060 Chiron (), provisional designation , and also known as 95P/Chiron, is a small solar system body (or minor planet) in the outer Solar System, orbiting the Sun between Saturn and Uranus.

Definition of planet spherical under its own gravity but not large enough to fuse. This definition would add 19 moons to the list of planets in our Solar System. The discovery since 1992 of extrasolar planets, or planet-sized objects around other stars ( such planets in planetary systems including multiple planetary systems as of ), has widened the debate on the nature of planethood in unexpected ways. Many of these planets are of considerable size, approaching the mass of small stars, while many newly discovered brown dwarfs are, conversely, small enough to be considered planets. The material difference between a low-mass star and
