763 Cupido (prov. designation: A913 SE or 1913 ST) is a Flora asteroid, tumbler and slow rotator from the inner regions of the asteroid belt, approximately 7 kilometers (4.3 miles) in diameter. It was discovered on 25 September 1913, by German astronomer Franz Kaiser at the Heidelberg-Königstuhl State Observatory in southwest Germany.[1] The S/L-type asteroid has an exceptionally long rotation period of 151 hours. It was named by its Latin name after Cupid, the Roman god of erotic love, attraction and affection.[3]
