1994 Shane, provisional designation 1961 TE, is a dark asteroid from the middle region of the asteroid belt, about 25 kilometers in diameter. It was discovered on 4 October 1961, by the Indiana Asteroid Program at Goethe Link Observatory near Brooklyn, Indiana, United States.[8]
The asteroid orbits the Sun at a distance of 2.1–3.2 AU once every 4 years and 5 months (1,602 days). Its orbit is tilted by 10 degrees to the plane of the ecliptic and shows an eccentricity of 0.21. The body takes about 8 hours to rotate once around its axis.[6] According to observations made by the Infrared Astronomical Satellite, IRAS, the asteroid has an albedo of 0.06,[4] while the survey carried out by the Japanese Akari satellite rendered a higher albedo of 0.13 with a corresponding diameter of 18 kilometers.[5] The Collaborative Asteroid Lightcurve Link derives an even lower albedo of 0.04, yet does not classify it as a carbonaceous but rather as a S-type asteroid, which typically have much higher albedos due to their stony surface composition.[3]
It was named after American astronomer Charles Donald Shane (1895–1983), director of Lick Observatory, second president of AURA, and instrumental for the establishment of the Cerro Tololo Inter-American Observatory in Chile. He played a major role in the planning and construction of the first telescopes and buildings on Kitt Peak National Observatory as well.[2]
