(10370) Chilonoma or Gilonoma ( lat. Hylonome ) - a small body of the solar system , whose orbit is located on the outer edge of the system. It belongs to the class of ice objects called Centaurs , whose orbit crosses the orbit of Neptune and touches the orbit of Uranus . Chilonoma was opened on February 27, 1995 . [1] The name is given in honor of the woman centaur of Chilonoma ( dr. Greek Υλονομη ). [5] [6]

Observations using the Spitzer infrared space telescope show that the diameter of the minor planet 10370 is 70 km ± 20 km (50 to 90 km in diameter) or 35 km in radius. [3]
Content
Orbit
The orbits of the bodies of the centaur family are unstable due to disturbances exerted by giant planets. Currently, Uranus controls the perihelion of Chilonoma, and Neptune controls his aphelion. [7] It is estimated that this is a relatively long orbital period with a half course of movement of about 6.37 million years. [7] In 3478, Chilonoma will pass at a distance of about ~ 85 Gm from Uranus and its semimajor axis of the orbit will decrease to 23.5 a.u. [eight]
