Pisces I

Pisces I or Pisces overdensity is a clump of stars in the Milky Way's halo, which may be a disrupted dwarf spheroidal galaxy. The galaxy is located at a distance of about 80 kpc from the Milky Way.

Pisces I is one of the faintest satellites of the Milky Way. Its mass is estimated to be at least 105 stellar masses. However it has a large size of around 1 kpc and may be in a transitional phase between a gravitationally bound galaxy and completely unbound system. It is located near the plane, where Magellanic Clouds lie. There may exist a connection between the Magellanic stream and this galaxy.
