7529 Vagnozzi, provisional designation1994 BC, is a stonyasteroid from the inner regions of theasteroid belt, approximately 5 kilometers in diameter. It was discovered on 16 January 1994, by and at theColleverde Observatory near Rome, Italy.[8] The asteroid was named for was named for Italian amateur astronomerAntonio Vagnozzi.[2]
Vagnozzi orbits the Sun in theinner main-belt at a distance of 2.2–2.7 AU once every 3 years and 10 months (1,407 days). Its orbit has aneccentricity of 0.12 and aninclination of 4° with respect to theecliptic.[1]It was first identified as1969 TK5 atCrimea–Nauchnij in 1969. The first used observation was taken at the AustralianSiding Spring Observatory in 1988, extending the asteroid'sobservation arc by 6 years prior to its official discovery.[8]
In August 2011, a tentative rotationallightcurve forVagnozzi was obtained from photometric observations by French amateur astronomerRené Roy. It gave a slower than averagerotation period of 36 hours (1.5 days) with a high brightness variation of0.740±0.029 inmagnitude, indicating a non-spheroidal shape (U=n/a).[6]
According to the survey carried out by theNEOWISE mission of NASA'sWide-field Infrared Survey Explorer,Vagnozzi measures 4.9 kilometers in diameter and its surface has analbedo of 0.29,[4] while theCollaborative Asteroid Lightcurve Link assumes a standard albedo forstony asteroids of 0.20 and calculates a diameter of 5.7 kilometers with anabsolute magnitude of 13.6.[3]
Thisminor planet was named in honor ofAntonio Vagnozzi (born 1950), an Italian amateur astronomer,discoverer of minor planets, and pioneer in using CCD cameras at theSanta Lucia Stroncone Astronomical Observatory in Italy. He is also an observer and discoverer ofsupernovae.[2][9] The official naming citation was published by theMinor Planet Center on 11 April 1998 (M.P.C. 31611).[10]
