GALAXY M82

Galaxies can oribt other galaxies, as in the case of M82 which orbits it nearby neighbor galaxy M81 once every several hundred million years.  Whereas M82 (not shown) is "face-on" for Earth observers, M81 is "edge-on."  This edge view causes its bright central region to be obscured by clouds of gas and dust.
