rotation period of 10.7 hours.[4]

Orbit and classification

2008 GO98 is classified as a member of the dynamical

centaur or trans-Neptunian object that ended its dynamical evolution as a quasi-Hilda comet.[3] It may have reached the belt during the last few hundred years.[7]

It orbits the Sun in the

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.[2] 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.[1]

Although 2008 GO98 orbits in the asteroid belt, it has a Jupiter Tisserand's parameter (TJ) of 2.926,[2] just below Jewitt's threshold of 3, which serves as a distinction between the main-belt asteroids (TJ larger than 3) and the Jupiter-family comets (TJ between 2 and 3).[8]

Numbering and naming

M.P.C. 98587).[9] As of 2020, it has not been named.[1]

Physical characteristics

2008 GO98 is an assumed C-type asteroid.[4]

Diameter and albedo

The Collaborative Asteroid Lightcurve Link assumes a standard

albedo for a carbonaceous body of 0.057 and calculates a diameter of 14.64 kilometers based on an absolute magnitude of 12.9.[4] Other estimates, taking into account several published magnitude measurements and a large range of albedo assumptions, estimate a diameter range of 5.5 to 24.7 kilometers.[5]
