Description of NGC 4147

Globular cluster NGC 4147 was discovered by William Herschel on March 14, 1784 and cataloged as H I.19.

This cluster is perhaps 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.
