1021 Flammario, provisional designation 1924 RG, is a dark background asteroid from the central regions of the asteroid belt, approximately 100 kilometers (62 miles) in diameter. It was discovered on 11 March 1924, by German astronomer Max Wolf at the Heidelberg-Königstuhl State Observatory in Heidelberg, Germany.[1] The asteroid was named after French astronomer Camille Flammarion.[2] The uncommon F-type asteroid has a rotation period of 12.16 hours.[4]
