(612093) 1999 LE31 prov. designation 1999 LE31 , is a centaur and damocloid on a retrograde and eccentric orbit from the outer region of the Solar System . It was first observed on 12 June 1999, by astronomers with the LINEAR program at the Lincoln Lab's ETS near Socorro, New Mexico, in the United States.[1] unusual object measures approximately 17 kilometers (11 miles) in diameter.[2] [3]
Description [ edit ]
1999 LE31 orbits the Sun at a distance of 4.3–11.9 AU semi-major axis of 8.13 AU ). Its orbit has an eccentricity of 0.47 and an inclination of 152° with respect to the ecliptic .[2]
It spends most of its orbit located in the outer Solar System between Jupiter and Uranus ,[5] [5] Jupiter and Saturn-crossing minor planet .[2] minor planets , 1999 LE31 is one of about 60 that has a retrograde orbit.[6]
1999 LE31 is approximately 16.8 km in diameter.[2] [3] perihelion (closest approach to the Sun) in December 1998.[7] [2]
