755 Quintilla (prov. designation: A908 GC or 1908 CZ) is a metallic background asteroid from the outer regions of the asteroid belt, approximately 36 kilometers (22 miles) in diameter. It was discovered on 6 April 1908, by American astronomer Joel Metcalf at the Taunton Observatory (803) in Massachusetts, United States. For its size, the M-type asteroid has a relatively short rotation period of 4.55 hours. It was named Quintilla, an Italian female first name, for no reason other than being the first asteroid name beginning with the letter "Q".
