Andromeda IV (Site not responding. Last check: 2007-10-26) |
 | | Andromeda IV was discovered within a survey by Sidney van der Bergh with the Palomar 48-inch (1.2-meter) Schmidt telescope, together with And I, And II, and And III (see van den Bergh 1972). |
 | | Investigations of 1991 have indicated that Andromeda IV might be a large, outlying open cluster or star cloud in M31, not an independent galaxy, as its stellar population is probably homogenously young, and it appeared from these measurements that this object participates in M31's galactic rotation (Jones 1993). |
 | | The moderate surface brightness reported here are consistent with And IV being a small dwarf irregular galaxy, perhaps similar to Local Group dwarfs such as IC 1613 and Sextans A. |
