William Herschel discovered NGC 5634 on March 5, 1785 and cataloged it as H I.70. This object is a considerably faint globular cluster.
This cluster is probably a former member of the Sagittarius Dwarf Elliptical Galaxy (SagDEG), or Sagittarius Dwarf Spheroidal Galaxy (Sgr dSph), the nearby dwarf galaxy discovered in 1994, which is currently in a close and perhaps final encounter before its tidal disruption, with our Milky Way Galaxy.
