2007 McCuskey, provisional designation 1963 SQ, is a larger mid-sized asteroid from the asteroid belt. It was discovered on 22 September 1963, by the Indiana Asteroid Program at Goethe Link Observatory near Brooklyn, Indiana, United States. The rather dark asteroid orbits the Sun at a distance of 2.1–2.7 AU once every 3.68 years (1,344 days). It has a rotation period of 8.6 hours.
Measurements made with the IRAS observatory give a diameter of 7001337900000000000♠33.79±1.31 kilometers and a geometric albedo of 6998700000000000000♠0.07±0.01. By comparison, measurements with Spitzer's Multiband Imaging Photometer (MIPS) give a diameter of 7001352600000000000♠35.26±3.74 kilometers and a geometric albedo of 6998300000000000000♠0.03±0.01.
It is named in honour of American mathematician and astronomer Sidney Wilcox McCuskey (1907–1979), who was the director of the Warner and Swasey Observatory and president of IAU Commission 33, Structure and Dynamics of the Galactic System. He is best known for his contribution on stellar luminosity and galactic structure.
