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.
