2065 Spicer, provisional designation 1959 RN, is a dark and eccentric asteroid from the middle region of the asteroid belt, about 17 kilometers in diameter. It was discovered by the Indiana Asteroid Program at the U.S. Goethe Link Observatory near Brooklyn, Indiana on 9 September 1959.[6]

It orbits the Sun at a distance of 2.1–3.3 AU once every 4 years and 5 months (1,618 days). Its orbit shows an eccentricity of 0.23 and is tilted by 6 degrees to the plane of the ecliptic. It has an albedo of 0.06.[4][3] The asteroid spectra is that of a X-type or Xc-type in SMASS classification scheme, which indicates a transitional stage to a C-type spectra of carbonaceous asteriods.

Photometric measurements of the asteroid made in 2005 at the Palmer Divide Observatory (see video in § External links) showed a light curve with a period of 18.165±0.005 hours and a brightness variation of 1.0±0.3 in magnitude.[5]

It is named after American anthropologist Edward H. Spicer (1906–1983), professor at the University of Arizona, and a former president of the American Anthropological Association. His assistance was a major factor in the success of the negotiations with the Schuk Toak District Council and the Papago Tribal Council in 1955 to obtain permission for the site evaluation of the later built Kitt Peak National Observatory.[2]
