Based on a recessional velocity of 8650 km/sec, pgc 762 is about 390 million light years away. By measuring their periods and their apparent brightnesses, he galaxies do not obey hubble's law exactly, because they have velocities of their own, in addition to their recessional velocity. The apparent recessional velocities of galaxies at large distances are due mainly to the actual motions of the galaxies through space. Given that and its apparent size of 0.5 by 0.5 arcmin, it is about 55 thousand light years across.
