Independently rediscovered by A.G. Wilson in 1955.
On various occasions, globular cluster
was taken for a nearby dwarf elliptical (or spheroidal) galaxy, and supposed
to be a Local Group member candidate because of its resolution into stars.
At its distance of 356,000 light years, this object is significantly more
remote than the nearest satellite galaxies of the Milky Way, namely SagDEG
and the Magellanic Clouds.
