A population study of galaxy satellites is performed using data from the Sloan Digital Sky Survey. The samples consist of about 30,000 `primary' galaxies with spectra and 750,000 `background' galaxies with photometrically determined redshifts. Potential satellites are found within 500 h-1 kpc of the primary galaxies, and a statistical background subtraction technique is used to determine the properties of those satellites. Preliminary results include satellite luminosity function and satellite radial distribution (correlation function) as functions of morphological type, luminosity, and redshift.
