17198 Gorjup, provisional designation 2000 AA31, is a stony Flora asteroid from the inner regions of the asteroid belt, approximately 2.7 kilometers in diameter. It was discovered by the Lincoln Near-Earth Asteroid Research team (LINEAR) at the U.S. Magdalena Ridge Observatory in Socorro, New Mexico, on 3 January 2000.[5]
The S-type asteroid is a member of the Flora family, one of the largest groups of stony asteroids in the main-belt. It orbits the Sun at a distance of 2.0–2.5 AU once every 3 years and 5 months (1,257 days). Its orbit has an eccentricity of 0.10 and an inclination of 3° with respect to the ecliptic.[1] The beginning of the asteroid's observation arc dates back to the a precovery taken at ESO's La Silla site in 1990.[5]
In 2008, a photometric light-curve analysis by Czech astronomer Petr Pravec at Ondřejov Observatory, near Prague, rendered a well-defined rotation period of 3.2430±0.0005 hours with a brightness variation of 0.12 in magnitude (U=3).[4] The Collaborative Asteroid Lightcurve Link assumes an albedo of 0.24, a typical value for asteroids with a stony surface composition, derived from the Flora family's largest member and namesake, the asteroid 8 Flora.[3]
The minor planet was named after Slovenian Niko Gorjup (b. 1984) an awardee in the Intel International Science and Engineering Fair (ISEF) in 2003. At the time, he attended the Solski Center Nova Gorica, Gimnazija, Nova Gorica, Slovenia.[2]
