Discovered by William Herschel on March 14, 1784.

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.

The image in this page was obtained by Martin Germano with an 8" f/5 Newtonian reflector and ST-8XME self-guided CCD camera and Lumicon Red filter. The larger image also shows the very thin background galaxy UGC 7170 situated in the apparent neighborhood.
