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.[2][8]

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.[1]

Physical characteristics

Spicer's spectra is that of an

NEOWISE mission.[4]

Photometry

In January 2005,

Diameter and albedo

According to the survey carried out by NASA's

albedo of 0.062,[4][5] 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.[3]

Naming

This 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.[2]

In 1955, Spicer's negotiations with the local district and tribal councils were instrumental for receiving permission to evaluate the location where the
