galactic rotation galaxy motion The revolving of a galaxy round its central nucleus even as it continues its proper motion. Such rotation, however, is not uniform but differential. One revolution of the Sun within our own Galaxy takes about 225 million years, or 1 cosmic year.

solar rotation length per unit time differential rotation Differential rotation, the equatorial rotation taking less time than the polar by up to 9.4 Earth-days.
