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.[1]

Measurements made with the IRAS observatory give a diameter of 33.79±1.31 kilometers and a geometric albedo of 0.07±0.01. By comparison, measurements with Spitzer's Multiband Imaging Photometer (MIPS) give a diameter of 35.26±3.74 kilometers and a geometric albedo of 0.03±0.01.[3]

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.[2]
