1754 Cunningham, provisional designation 1935 FE, is a dark, reddish Hildian asteroid from the outermost region of the asteroid belt, about 80 kilometers in diameter. It was discovered by Belgian astronomer Eugène Delporte at the Royal Observatory of Belgium in Uccle, on 29 March 1935.[10]
The asteroid is a member of the Hilda family, a large group that orbits in resonance with the gas giant Jupiter and are thought to originate from the Kuiper belt. As of 2015, it belongs to a small group of 33 known asteroids with a spectral P-type in the Tholen classification scheme.[11] It orbits the Sun at a distance of 3.3–4.6 AU once every 7 years and 10 months (2,855 days). Its orbit shows an eccentricity of 0.17 and is tilted by 12 degrees to the plane of the ecliptic. It has a rotation period of 7.4 hours[8][9] and a very low albedo of 0.03, according to surveys carried out by the Infrared Astronomical Satellite, IRAS, and the Japanese Akari space mission.[5][6]
The minor planet was named in honor of American astronomer Leland Cunningham (1904–1989), who began his career as an assistant to astronomer Fred Whipple (also see 1940 Whipple) at Harvard University in the 1930s and worked at the Leuschner Observatory of University of California during the 1940s and 1950s. Cunningham discovered four minor planets himself and was a prolific computer of cometary orbits and observer of faint comets, including comet Gale, a lost comet he recovered in 1938.[2]
