Pisces Dwarf is an irregular dwarf galaxy that is part of the Local Group. The galaxy is also suspected of being a satellite galaxy of the Triangulum Galaxy (M33). Because it is in the constellation Pisces, the galaxy is called the Pisces Dwarf. It displays a blueshift, as it is approaching the Milky Way at 287 km/s. It may be transition-type galaxy, somewhere between dwarf spheroidal and dwarf irregular alternatively, it may be a rare, but statistically acceptable, version of one of the two types.[2]
[edit] History
It was discovered by Karachentseva in 1976.[2]
