7517 Alisondoane, provisional designation 1989 AD, is a carbonaceous asteroid from the inner regions of the asteroid belt, about 9 kilometers in diameter. It was discovered on 3 January 1989, by Japanese amateur astronomer Takuo Kojima at the YGCO Chiyoda Station in the northern Kantō region of Japan.[6]
The C-type asteroid orbits the Sun at a distance of 1.8–3.1 AU once every 3 years and 10 months (1,398 days). Its orbit shows an eccentricity of 0.26 and an inclination of 6 degrees from the plane of the ecliptic.[1] A photometric light-curve analysis by Czech astronomer Petr Pravec in 2007 rendered a rotation period of 9.701±0.001 hours with a high brightness amplitude of 1.13 in magnitude (U=3).[lower-alpha 1]
Based on observations by the Japanese Akari satellite and the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, the asteroid has an albedo of 0.128 and 0.122 with a diameter of 9.3 and 9.1 kilometers, respectively.[4][5] The Collaborative Asteroid Lightcurve Link (CALL) calculates a smaller diameter of 5.4 kilometers based on an assumed albedo of 0.20, untypically high for a carbonaceous asteroid.[3]
The minor planet was named in honor of Alison Doane (b. 1958) a curator of astronomical photographs at the Harvard College Observatory. She was also principal oboe with the Boston Philharmonic Orchestra from 1982 to 2001.[6]
