683 Lanzia is a minor planet orbiting the Sun. It was discovered July 23, 1909 by Max Wolf at the Landessternwarte Heidelberg-Königstuhl observatory[2] and was named after the fungus Lanzia. Photometric observations made in 2003 at the Santana Observatory in Rancho Cucamonga, California give a synodic rotation period of 8.63 ± 0.005 hours. The light curve shows a brightness variation of 0.15 ± 0.04 in magnitude.[2]

Observations during two last occultation 18 and 22 December 2010 (P.Baruffetti, G. Tonlorenzi - Massa, G. Bonatti - Carrara, R. Di Luca - Bologna (Italy), C. Schnabel - S. Estebe, J. Rovira - Moja (Spain)) mesured a 122.5 km diameter (medium) and an Albedo of 0.0705 compatible with carbonaced asteroids (C group).
