17035 Velichko (provisional designation1999 FC10) is a Vestianasteroid from the inner regions of theasteroid belt, approximately 4.5 kilometers in diameter.
It was discovered on 22 March 1999, byLONEOS program at Lowell'sAnderson Mesa Station near Flagstaff, Arizona, United States.[9] The asteroid was named after Ukrainian astronomerFedor Velichko.
Velichko is a core member of theVesta family, thought to have originated from theRheasilvia crater, a largeimpact crater on the south-polar surface of4 Vesta, which is the main-belt's second-most-massive asteroid after1 Ceres.
It orbits the Sun in theinner main-belt at a distance of 2.1–2.8 AU once every 3 years and 10 months (1,395 days). Its orbit has aneccentricity of 0.15 and aninclination of 6° with respect to theecliptic.[1]
The asteroid'sobservation arc begins 10 years prior to its official discovery observation, with its identification as1989 TD2 at ESO'sLa Silla Observatory in October 1989.[9]
Velichko has been characterized as a brightV-type asteroid byPan-STARRS photometric survey.[8]
Two photometriclightcurves of Velichko were obtained by French astronomerRené Roy at the Blauvac Observatory (627) in France, and by astronomers at thePalomar Transient Factory in California. Lightcurve analysis gave arotation period of2.899 and2.8990 hours with a brightness variation of 0.23 and 0.29magnitude, respectively (U=2/2).[7][6]
According to the survey carried out by theNEOWISE mission of NASA's space-basedWide-field Infrared Survey Explorer, Velichko has a diameter of 4.8 kilometers and analbedo of 0.28.[4] TheCollaborative Asteroid Lightcurve Link assumes a much higher albedo of 0.40, which is typical value for the bright stony surface of Vestian asteroids, and calculates a shorter diameter of 4.2 kilometers.[3]
Thisminor planet was named after Ukrainian astronomer Fedor P. Velichko (1957–2013), who was a senior scientist at the Institute of Astronomy of the UkrainianNational University of Kharkiv, and director of the University'sChuguev Observing Station (131), also known as theChuguevskaya Station. He was an expert on thephotometry andpolarimetry ofsmall Solar System bodies.[2] The official naming citation was published by theMinor Planet Center on 21 July 2005 (M.P.C. 54563).[10]
