17163 Vasifedoseev, provisional designation 1999 LT19, is a stony Koronian asteroid from the outer region of the asteroid belt, approximately 4 kilometers in diameter. It was discovered on 9 June 1999, by the Lincoln Near-Earth Asteroid Research team (LINEAR) at the U.S. Lincoln Laboratory Experimental Test Site in Socorro, New Mexico.[8]

The S-type asteroid is a member of the Koronis family, a group consisting of about 300 known bodies. It orbits the Sun at a distance of 2.7–3.1 AU once every 4 years and 11 months (1,807 days). Its orbit has an eccentricity of 0.08 and an inclination of 1° with respect to the ecliptic.[1] The first precovery was obtained at ESO's La Silla Observatory in 1990, extending the asteroid's observation arc by 9 years prior to its discovery.[8]

A rotational light-curve for this asteroid was obtained from photometric observations by the wide-field survey at the U.S. Palomar Transient Factory in September 2010. The light-curve rendered a rotation period of 4.1124±0.0006 hours with a brightness variation of 0.23 in magnitude (U=2).[6] According to the survey carried out by the NEOWISE mission of NASA's space-based Wide-field Infrared Survey Explorer, the asteroid measures 4.9 kilometers in diameter and its surface has an albedo of 0.17,[4][5] while the Collaborative Asteroid Lightcurve Link assumes an albedo of 0.24 and calculates a diameter of 3.7 kilometers.[3]

The minor planet was named after Russian Vasiliy G. Fedoseev (b. 1986) an awardee of the Intel International Science and Engineering Fair (ISEF) in 2003. At the time, he attended the Lyceum of Information Technologies Moscow, Russia.[2] Naming citation was published on 14 June 2004 (M.P.C. 52172).[9]
