10370 Hylonome is an asteroid orbiting in the farther part of the solar system. It belongs to the group of icy minor planets called centaurs, with an orbit that crosses the orbits of Neptune and Uranus. It was found on February 27, 1995.
Sightings with the Spitzer Space Telescope show that it's diameter is about 70 km (43 miles) plus or minus 20 km (50 to 90 km in diameter), or a 35 km radius.
Naming
This minor planet was named for Hylonome, a female centaur in Greek mythology. In the epic tragedy, she lost her very much beloved husband, the handsome centaur Cyllarus, who was accidentally killed by a spear. Heartbroken, she then took her own life to join him by throwing herself on the spear. The official naming citation was published on 26 July 2000 (M.P.C. 41030).
