'''10370 Hylonome''' ({{IPAc-en|icon|h|aɪ|ˈ|l|ɒ|n|ə|m|iː}}; from {{Lang-el|''‘Υλονομη''}}) là một [[small Solar System body]] orbiting in the outer Solar System. It belongs to the class of icy objects that are known as [[centaur (minor planet)|centaur]]s, with an orbit that crosses the orbit of [[Neptune]] and [[list of Uranus-crossing minor planets|grazes that of]] [[Uranus]]. It được khám phá on February 27, 1995.<ref name="MPC"/>

10370 Hylonome was named for [[Hylonome]], a female [[centaur]] in [[Greek mythology]].

Observations with the infrared [[Spitzer Space Telescope]] show a diameter of 10370 to be {{convert|70|km|mi|abbr=on}} plus or minus 20&nbsp;km (50 to 90&nbsp;km in diameter), or a 35&nbsp;km radius.<ref name="spitzer">

The orbits of centaurs are unstable due to [[Perturbation (astronomy)|perturbations]] by the giant planets.  Currently Uranus controls Hylonome's [[Apsis|perihelion]] and Neptune its aphelion.<ref name=Horner2004a/> It is estimated to have a relatively long orbital half-life of about 6.37 [[Myr]].<ref name=Horner2004a>{{cite journal
