10370 Hylonome (Template:PronEng, from [‘Υλονομη] Error: {{Lang-xx}}: text has italic markup (help)) is an asteroid orbiting in the outer solar system. It belongs to the class of icy planetoids that are known as centaurs, with an orbit that crosses the orbits of Neptune and Uranus. It was discovered on February 27, 1995.[1]
Observations with the infrared Spitzer Space Telescope show a diameter of 10370 to be 70 km (43 miles) plus or minus 20 km (50 to 90 km in diameter), or a 35 km radius.[3]
Orbit
The orbits of centaurs are unstable due to perturbations by the giant planets. Hylonome is an UN object since currently Uranus controls the perihelion and Neptune controls the aphelion.[5] Hylonome is estimated to have a relatively long orbital half-life of about 6.37 Myr.[5] In the year 3478, Hylonome will pass within ~85Gm of Uranus and its semi-major axis will be reduced to 23.5AU.[6]
