6398 Timhunter
6398 Timhunter, provisional designation , is a stony Phocaea asteroid from the inner regions of the asteroid belt, approximately 5.5 kilometers in diameter. It was discovered on 10 February 1991, by American astronomer couple Carolyn and Eugene Shoemaker, in collaboration with Canadian astronomer David H. Levy at Palomar Observatory in California, United States. It was named for American amateur astronomer Tim Hunter. Classification an orbit The stony S-type asteroid is a member of the Phocaea family (), a relatively small group of asteroids with similar orbital characteristics. Timhunter orbits the Sun in the inner main-belt at a distance of 1.8–2.9 AU once every 3 years and 7 months (1,310 days). Its orbit has an eccentricity of 0.22 and an inclination of 24° with respect to the ecliptic. It was first identified as at Goethe Link Observatory in 1955, extending the body's observation arc by 36 years prior to its official discovery observation at Palomar. Lightcurves In March 2009, a rotational lightcurve of Timhunter was obtained from photometric observations by astronomer Petr Pravec at the Ondřejov Observatory in the Czech Republic. Lightcurve analysis gave a well-defined rotation period of 14.55 hours with a brightness variation of 0.29 magnitude (). One month
