7517 Alisondoane, provisional designation 1989 AD, is a carbonaceous asteroid from the inner regions of the asteroid belt, approximately 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.
Orbit and classification [ ]
Alisondoane orbits the Sun in the inner main-belt at a distance of 1.8–3.1 AU once every 3 years and 10 months (1,397 days). Its orbit has an eccentricity of 0.26 and an inclination of 6 ° with respect to the ecliptic.
Physical characteristics [ ]
Alisondoane has been characterized as a carbonaceous C-type asteroid by PanSTARRS photometric survey.
Lightcurves [ ]
lightcurve analysis by Czech astronomer Petr Pravec in 2007 rendered a rotation period of hours with a high brightness amplitude of 1.13 in 9.701 ±0.001 magnitude ( ). U=3
Diameter and albedo [ ]
According to the surveys carried out by the Japanese
Akari satellite and NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Alisondoane measures between 8.52 and 9.99 kilometers in diameter and its surface has an albedo between 0.04 and 0.122.      The  Collaborative Asteroid Lightcurve Link (CALL) calculates a smaller diameter of 5.16 kilometers based on an assumed albedo of 0.18 for a X-type asteroid. 
Naming [ ]
minor planet was named in honor of Alison Doane (born 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. The official naming citation was published by the  Minor Planet Center on 25 December 2015 ( ). M.P.C. 97567

^ a b Pravec (2007): rotation period
hours with a brightness amplitude of 9.701 ±0.001 mag. CALL assigns a "Quality Code" of 3, which denotes a secure result within the precision given and no ambiguity. Summary figures for (7517) Alisondoane at 1.13 Collaborative Asteroid Lightcurve Link (CALL)
