    1373 Cincinnati, provisional designation 1935 QN, is an asteroid of the outer asteroid belt, approximately 20 kilometers in diameter. It was discovered by the famous American astronomer Edwin Hubble at Mount Wilson Observatory on August 30, 1935. It was his only asteroid discovery.

    Orbit and characterization

    The X-type asteroid has an extremely inclined, cometary-like orbit of 39 degrees to the ecliptic.[1][4] Cincinnati is similar to the Cybele asteroids.[5]

    Naming

    Recommended by the Minor Planet Center, the asteroid is named after the Cincinnati Observatory, whose staff provided most of the orbit computations.[1]
