[2] Cunningham is a dark and reddish asteroid and 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.
[3] In July 2015, a rotational lightcurve of Cunningham was obtained from photometric observation by American amateur astronomer Robert Stephens at the Center for Solar System Studies in California.
[9] A similar period of 7.7398 hours with an amplitude of 0.16 was previously obtained by French and Italian amateur astronomers Pierre Antonini and Silvano Casulli in July 2008 (U=2).
[5][6] The Collaborative Asteroid Lightcurve Link agrees with the results found by IRAS, that is an albedo of 0.035 and a diameter of 79.52 kilometers with on an absolute magnitude of 9.77.
[4] Cunningham belongs to a small group asteroids with a spectral P-type in the Tholen classification scheme.
