(457175) 2008 GO98

Orbit and classification

2008 GO₉₈ 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 (2,883 days; semi-major axis of 3.96 AU). 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 2008 GO₉₈ orbits in the asteroid belt, it has a Jupiter Tisserand's parameter (T_J) of 2.926, just below Jewitt's threshold of 3, which serves as a distinction between the main-belt asteroids (T_J larger than 3) and the Jupiter-family comets (T_J between 2 and 3).
