2065 Spicer, provisional designation 1959 RN, is a dark and eccentric asteroid from the middle region of the asteroid belt, approximately 17 kilometers in diameter.
The asteroid was discovered on 9 September 1959, by the
Indiana Asteroid Program at Goethe Link Observatory near Brooklyn, Indiana, United States, and named after American anthropologist Edward H. Spicer. 
Orbit and classification
Spicer orbits the Sun in the central main-belt at a distance of 2.1–3.3 AU once every 4 years and 5 months (1,619 days). Its orbit has an eccentricity of 0.23 and an inclination of 6 ° with respect to the ecliptic.
Spicer 's spectra is that of a X-type and Xc-type in SMASS classification scheme, which indicates a transitional stage to the carbonaceous C-type asteroid. It has also been characterized as a  P-type asteroid by the NEOWISE mission.
In January 2005,
photometric measurements of Spicer made by American astronomer Brian Warner at the Palmer Divide Observatory ( ) gave a 716 lightcurve with a well-defined rotation period of hours and a brightness variation of 18.165 ±0.005 1.0 ±0.03 magnitude ( ). U=3 
Diameter and albedo
According to the survey carried out by NASA's
Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Spicer measures 16.721 kilometers in diameter and its surface has an albedo of 0.062,  while the  Collaborative Asteroid Lightcurve Link assumes a standard albedo for carbonaceous asteroids of 0.057 and calculates a diameter of 18.43 kilometers with an absolute magnitude of 12.4.
minor planet was named after American anthropologist Edward H. Spicer (1906–1983), professor at the University of Arizona, and a former president of the American Anthropological Association.
In 1955, Spicer's negotiations with the local district and tribal councils were instrumental for receiving permission to evaluate the location where the
Kitt Peak National Observatory was later built. The official naming citation was published by the  Minor Planet Center on 26 May 1983 ( ). M.P.C. 7944
