2060 Chiron
2060 Chiron, also known as 95P/Chiron, is a minor planet in the outer Solar System, orbiting between Saturn and Uranus. Discovered in 1977 by Charles T. Kowal (precovery images have been found as far back as 1895),〔 it was the first-identified member of a new class of objects now known as centaurs—bodies orbiting between the asteroid belt and the Kuiper belt.〔944 Hidalgo, discovered in 1920, also fits this definition, but was not identified as belonging to a distinct population.〕 Besides the four gas giants, Chiron and 10199 Chariklo, also a centaur, are the only bodies in the Solar System known to have rings.〔
Although it was initially called an asteroid and classified only as a minor planet with the designation "2060 Chiron", it was later found to exhibit behavior typical of a comet. Today it is classified as both a minor planet and a comet, and is accordingly also known by the cometary designation "95P/Chiron".
Chiron is named after the centaur Chiron in Greek mythology.
Michael Brown lists it as possibly a dwarf planet with a measured diameter of 206 km,〔 which is near the lower limit for an icy dwarf planet (around 200 km).
