Pisces Dwarf
From Wikipedia, the free encyclopedia
This article is about the suspected satellite galaxy of the Triangulum Galaxy. For other dwarf galaxies labelled Pisces, see Pisces (disambiguation).
The Pisces Dwarf, also known as Pisces I,[1] is an irregular dwarf galaxy that is part of the Local Group. The galaxy, taking its name from the constellation Pisces where it appears, is suspected of being a satellite galaxy of the Triangulum Galaxy (M33). 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]
