1373 Cincinnati, provisional designation 1935 QN, is an asteroid in a comet-like orbit from the Cybele region, located at the outermost rim of the asteroid belt, approximately 20 kilometers (12 miles) in diameter. It was the only asteroid discovery made by famous American astronomer Edwin Hubble, while observing distant galaxies at Mount Wilson Observatory in California on 30 August 1935. The rather spherical X-type asteroid has a rotation period of 5.3 hours. It was named for the Cincinnati Observatory.
