(457175) 2008 GO98
with cometary number 362P, is a Jupiter family comet in a quasi-Hilda orbit within the outermost regions of the asteroid belt. It was discovered on 8 April 2008, by astronomers of the Spacewatch program at Kitt Peak National Observatory near Tucson, Arizona, in the United States. This presumably carbonaceous body has a diameter of approximately and rotation period of 10.7 hours.
Orbit and classification
is classified as a member of the dynamical Hilda group, as well as a Jupiter family that shows clear cometary activity, which has also been described as a "quasi-Hilda comet". Orbital backward integration suggests that it might have been a centaur or trans-Neptunian object that ended its dynamical evolution as a quasi-Hilda comet. It may have reached the belt during the last few hundred years.It orbits the Sun in the outer asteroid belt at a distance of 2.9–5.1 AU once every 7 years and 11 months. Its orbit has an eccentricity of 0.28 and an inclination of 16° with respect to the ecliptic. The body's observation arc begins with a precovery taken by the Sloan Digital Sky Survey in October 2001, more than 5 years prior to its official discovery observation by Spacewatch.
Although orbits in the asteroid belt, it has a Jupiter Tisserand's parameter of 2.926, just below Jewitt's threshold of 3, which serves as a distinction between the main-belt asteroids and the Jupiter-family comets.
