6377 Cagney, provisional designation 1987 ML1, is a carbonaceous Eunomia asteroid from the middle region of the asteroid belt, about 9 kilometers in diameter. It was discovered on 25 June 1987, by Czech astronomer Antonín Mrkos at South Bohemian Kleť Observatory in the Czech Republic.[6]
The C-type asteroid is a member of the Eunomia family, the most prominent family of otherwise stony asteroids in the intermediate main-belt. It orbits the Sun at a distance of 2.2–3.0 AU once every 4 years and 3 months (1,550 days). Its orbit has an eccentricity of 0.16 and an inclination of 15° with respect to the ecliptic.[1]
In February 2008, a photometric light-curve analysis by Slovak astronomer Adrián Galád at the Modra Observatory gave a rotation period of 4.171±0.003 hours with a brightness amplitude of 0.20 in magnitude (U=3).[4] The Collaborative Asteroid Lightcurve Link (CALL) assumes an albedo of 0.21 (which is typical for stony asteroids) and calculates a diameter of 9.2 kilometers.[3]
The minor planet was named in memory of American actor and dancer James Cagney (1899–1986), remembered best for playing multifaceted tough guys in movies such as The Public Enemy (1931) and Angels with Dirty Faces (1938). In 1942, Cagney won the Oscar for his energetic portrayal of George M. Cohan in Yankee Doodle Dandy.[2]
