Questions about centaurs, small Solar System bodies with orbits between Jupiter and Neptune.
Centaurs are a class of small solar system bodies located between the orbits of Jupiter and Neptune. The first identified member of the class was (2060) Chiron, also designated as a periodic comet under the designation 95P/Chiron. The object was named after Chiron, the wisest of the centaurs in Greek mythology.
The IAU Minor Planet Center defines centaurs as having perihelia beyond the orbit of Jupiter and semimajor axes inside the orbit of Neptune. The JPL Small-Body Database defines centaurs as having semimajor axes between the orbits of Jupiter (5.5 AU) and Neptune (30.1 AU). Both of these definitions include the Uranus trojans 2011 QF99 and 2014 YX49.
