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.
The S-type asteroid orbits the Sun 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.Vagnozzi 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.
In August 2011, a tentative rotational light-curve 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).
According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, the asteroid measures 4.9 kilometers in diameter and its surface has an albedo of 0.29, while the Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and calculates a diameter of 5.7 kilometers based on an absolute magnitude of 13.6.
