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.
