1312 Vassar
1312 Vassar, provisional designation 1933 OT, is a carbonaceous asteroid from the outer region of the asteroid belt, about 36 kilometers in diameter. It was discovered by Belgian–American astronomer George Van Biesbroeck at the U.S Yerkes Observatory in Williams Bay, Wisconsin, on 27 July 1933.〔 The dark C-type asteroid orbits the Sun at a distance of 2.4–3.8 AU once every 5 years and 5 months (1,989 days). Its orbit shows an eccentricity of 0.22 and is tilted by 22 degrees to the plane of the ecliptic. It has a rotation period of 7.9 hours and an albedo between 0.06 and 0.08, based on the surveys carried out by the Infrared Astronomical Satellite, IRAS, and the Japanese Akari satellite.〔〔 The minor planet was named by American female astronomer Maud Worcester Makemson (1891–1977) after the U.S Vassar College (formerly: Vassar Female College), located in New York state. Makemson, who computed the asteroid's orbit, was a teacher at the private elite school and director of its Vassar College Observatory.〔 == References ==
