735 Marghanna (prov. designation: A912 XD or 1912 PY) is a large carbonaceous background asteroid from the central regions of the asteroid belt, approximately 74 kilometers (46 miles) in diameter. It was discovered on 9 December 1912, by German astronomer Heinrich Vogt at the Heidelberg-Königstuhl State Observatory in southwest Germany.^[1] The dark C-type asteroid (Ch) has a rotation period of 20.6 hours and is rather regular in shape. It was named after Margarete Vogt and after Hanna, the mother and a relative of the discoverer, respectively.^[2]
