Summary
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 in honor of Lanz, founder of the Heidelberg Academy of Sciences. 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]
