Physical characteristics

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.[1]

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.[3]
