944 Hidalgo /hɪˈdælɡoʊ/ is a centaur and unusual object on an eccentric, cometary-like orbit between the asteroid belt and the outer Solar System, approximately 52 kilometers (32 miles) in diameter. Discovered by German astronomer Walter Baade in 1920, it is the first member of the dynamical class of centaurs ever to be discovered. The dark D-type object has a rotation period of 10.1 hours and likely an elongated shape.[9] It was named after Mexican revolutionary Miguel Hidalgo y Costilla.[3]
