Centaurs will thus ultimately collide with the Sun or a planet or else they may be ejected into interstellar space after a close approach to one of the planets, particularly Jupiter. There are numerous theories to explain this colour difference, but they can be divided broadly into two categories:. A dozen known centaurs follow retrograde orbits. A tidally-evolved binary Centaur”. For selected objects, the eccentricity of the orbits is represented by red segments extending from perihelion to aphelion.

It is thus now officially classified as both a comet and an asteroidalthough it is far larger than a typical cfntaur-p and there is some lingering controversy. Minimum monthly payments are required.

Thus far, only the binary objects Ceto and Phorcys and Typhon and Echidna have been named according to the new policy. Befitting their centaur-like transitional orbits between TNOs and comets, “objects on unstable, non-resonant, giant-planet-crossing orbits with semimajor axes greater than Neptune’s” are to be named for other hybrid and shape-shifting mythical creatures.


Any centaur that is perturbed close enough to the Sun is expected to become centwur-p comet. Annual Review of Astronomy and Astrophysics.

Observations of Chiron in and near its perihelion found it to display a coma a cloud of gas and dust evaporating from its surface. Plutinos are a class of Kuiper belt object that display a similar bicoloured nature, and centayr-p are suggestions that not all plutinos’ orbits are as stable as initially thought, due to perturbation by Pluto.
