7 Essential Words of Fall
wisest of the centaurs, from Latin Chiron, from Greek Kheiron, of unknown origin; Klein compares Greek kheirourgos "surgeon."
A large cometlike body with an orbit mostly between Saturn and Uranus. Discovered in 1977, Chiron was originally identified as an asteroid, but it has since been reclassified as a Centaur. Like a comet, Chiron has been observed to display a nebulous coma in its closest approach to the Sun, but at approximately 200 km (124 mi) in diameter it is far larger than any other known comet.
