[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).
[8] 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] 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] This minor planet was named in honor of Antonio Vagnozzi (born 1950), an Italian amateur astronomer, discoverer of minor planets, and pioneer in using CCD cameras at the Santa Lucia Stroncone Astronomical Observatory in Italy.
