10370 Hylonome (//; from Greek: ‘Υλονομη) is a small Solar System body orbiting in the outer Solar System. It belongs to the class of icy objects that are known as centaurs, with an orbit that crosses the orbit of Neptune and grazes that of Uranus. It was discovered on February 27, 1995.
The orbits of centaurs are unstable due to perturbations by the giant planets. Currently Uranus controls Hylonome's perihelion and Neptune its aphelion. It is estimated to have a relatively long orbital half-life of about 6.37 Myr. In the year 3478, Hylonome will pass within ~85 Gm of Uranus and its semi-major axis will be reduced to 23.5 AU.
