2065 Spicer, provisional designation Template:Mp, 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.[1][2]
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.[3]
Physical characteristics
SpicerTemplate:'s spectra is that of an X-type and Xc-type in SMASS classification scheme, which indicates a transitional stage to the carbonaceous C-type asteroid.[3] It has also been characterized as a P-type asteroid by the NEOWISE mission.[4]
Photometry
In January 2005, photometric measurements of Spicer made by American astronomer Brian Warner at the Palmer Divide Observatory (716Script error: No such module "Check for unknown parameters".) gave a lightcurve with a well-defined rotation period of Template:Val hours and a brightness variation of Template:Val magnitude (U=3Script error: No such module "Check for unknown parameters".).[5]Template:Efn
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,[4][6] 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.[7]
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.[1]
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.[1] The official naming citation was published by the Minor Planet Center on 26 May 1983 (M.P.C. 7944Script error: No such module "Check for unknown parameters".).[8]
