2013 LA2 is a Centaur and most likely an extinct comet with the highest orbital inclination of any known asteroid, 175.189 degrees, which gives it a retrograde orbit, inclined 4.81 degrees to the ecliptic. The asteroid's orbit takes if from the outer main asteroid belt to between the orbit of Saturn and Uranus. However the asteroid's orbit is poorly determined, and contrary to the JPL, the minor planet center's orbit puts it with an aphelion near the orbit of Saturn. The asteroid was observed 43 times over a 25-day interval between June 1, 2013 and June 26, 2013.
