7529 Vagnozzi, provisional designation 1994 BC, is a stony asteroid from the inner regions of the asteroid belt, approximately 5 kilometers in diameter. It was discovered on 16 January 1994, by and at the Colleverde Observatory near Rome, Italy.[8] The asteroid was named for was named for Italian amateur astronomer Antonio Vagnozzi.[2]
Vagnozzi orbits the Sun in the inner main-belt at a distance of 2.2–2.7 AU once every 3 years and 10 months (1,407 days). Its orbit has an eccentricity of 0.12 and an inclination of 4° with respect to the ecliptic.[1] It was first identified as 1969 TK5 at Crimea–Nauchnij in 1969. The first used observation was taken at the Australian Siding Spring Observatory in 1988, extending the asteroid's observation arc by 6 years prior to its official discovery.[8]
Physical characteristics
Rotation period
In August 2011, a tentative rotational lightcurve for Vagnozzi was obtained from photometric observations by French amateur astronomer René Roy. It gave a slower than average rotation period of 36 hours (1.5 days) with a high brightness variation of 0.740±0.029 in magnitude, indicating a non-spheroidal shape (U=n/a).[6]
Diameter and albedo
According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Vagnozzi measures 4.9 kilometers in diameter and its surface has an albedo of 0.29,[4] while the Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and calculates a diameter of 5.7 kilometers with an absolute magnitude of 13.6.[3]
