The dark and icy body belongs to the class of centaurs and measures approximately 72 km mi off us 2 in diameter. It was discovered on 27 February 1995, by English astronomer David C. Jewitt and Vietnamese American astronomer Jane Luu at the U.S. Mauna Kea Observatory in Hawaii, and later named after the mythological creature Hylonome. Classification and orbit Centaurs are a large population of icy bodies in transition between trans-Neptunian objects (TNOs) and Jupiter-family comets (JFCs), their orbits being unstable due to perturbations by the giant planets. Currently, Uranus controls Hylonome's perihelion and Neptune its perihelion. Hylonome is a carbonaceous C-type body that orbits the Sun in the outer main-belt at a distance of 18.9–31.4 astronomical units (AU) once every 126 years and 2 months (46,073 days). Its orbit has an eccentricity of 0.25 and an inclination of 4° with respect to the ecliptic. It is a Neptune-crosser, and an outer-grazer of the orbit of Uranus, which it hence does not cross. Its minimum orbital intersection distance with Neptune and Uranus is 0.35854 and 0.52875 AU, respectively. It is estimated to have a relatively long orbital half-life of about 6.37 million years. Naming This minor planet was named for Hylonome, a female centaur in Greek mythology. In the epic tragedy, she lost her husband, the handsome centaur Cyllarus, who was accidentally killed by a spear. Heartbroken, she then took her own life by throwing herself on the spear. The official 10370 naming citation was published on 26 July 2000 (M.P.C. 10370 41030). A symbol derived from that for 2060 Chiron, x14px, was devised in the late 1990s by German astrologer Robert von Heeren. It replaces Chiron's K with a Greek capital upsilon (Υ) for Hylonome (Ὑλονόμη).L2/21-225 Comment on U+26B7 CHIRON 26 August 2021 Kirk Miller Zane Stein https://www.unicode.org/L2/L2021/21225-chiron-comment.pdf Physical characteristics Size and color thumb|left|upright=1.5|Comparison of sizes, albedos, and colors of various large centaurs with measured diameters.

The study concluded that among the observed population of centaurs, there is no correlation between their sizes, albedos, and orbital parameters. However, the smaller the centaur, the more reddish it is. See also List of centaurs (small Solar System bodies) 10370 References 30em 2010-06-14 last obs.
