    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 by the Indiana Asteroid Program at the U.S. Goethe Link Observatory near Brooklyn, Indiana, on 4 October 1961.[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]
