(457175) 2008 GO98 provisional designation 2008 GO98 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.[1] rotation period of 10.7 hours.[4]
Orbit and classification [ edit ]
2008 GO98 is classified as a member of the dynamical Hilda group ,[4] Jupiter family that shows clear cometary activity,[6] [5] [3] centaur or trans-Neptunian object that ended its dynamical evolution as a quasi-Hilda comet.[3] [7]
It orbits the Sun in the outer asteroid belt at a distance of 2.9–5.1 AU 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] 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 (T J [2] Jewitt's threshold of 3, which serves as a distinction between the main-belt asteroids (T J T J [8]
Numbering and naming [ edit ]
This minor planet was numbered by the Minor Planet Center on 16 February 2016 (M.P.C. 98587[9] named .[1]
Physical characteristics [ edit ]
2008 GO98 is an assumed C-type asteroid .[4]
Rotation period [ edit ]
In August 2017, a rotational lightcurve of 2008 GO98 was obtained from photometric observations by American astronomer Brian Warner at the Palmer Divide Station (U82 rotation period of ± 0.01magnitude (U=2 [4] [a]
Diameter and albedo [ edit ]
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] [5]
