2013 LA2 centaur and damocloid on a cometary-like and retrograde orbit from the outer Solar System , suggesting that it is an extinct comet . It was first observed on 1 June 2013 by astronomers with the Pan-STARRS survey at Haleakala Observatory , Hawaii, in the United States.[1] [3] highest orbital inclination of any known minor planet .
Orbit and classification
[ edit ]
2013 LA2 AU semi-major axis of 7.51 AU ). Its orbit has an eccentricity of 0.59 and an inclination of 175° with respect to the ecliptic .[2]
It has the highest orbital inclination of any known minor planet which gives it a retrograde orbit . The objects's orbit takes it from the outer region of the asteroid belt to between the orbit of Saturn (9.5 AU ) and Uranus (19.2 AU ). The body's short observation arc of less than a month begins with its first observation on 1 June 2013. It has not since been observed.[1]
Physical characteristics
[ edit ]
Johnston's archive assumes an albedo 0.09 and calculates a diameter of 1.8 kilometers.[3]
