The Pisces Dwarf, also known as Pisces I (Psc I) or LGS3, is an irregular dwarf galaxy and suspected satellite galaxy of the Triangulum Galaxy (M33), located within the Pisces constellation. Discovered by astronomer Valentina Karachentseva in 1976, it is approaching the Milky Way at 287 km/s, evident by its blueshift, and may be a galaxy currently transitioning between a dwarf spheroidal and dwarf irregular galaxy; alternatively, it may be a rare unique version of one of the two types.
