NGC 6501 is a 12.4 mag bright lenticular galaxy of the Hubble type S0 / a in the constellation Hercules in the northern sky . It is estimated to be 144 million light years from the Milky Way and about 75,000 light years in diameter . Together with NGC 6500 , it forms the isolated, gravitationally bound galaxy pair KPG 526 .
She is considered a member of the six galaxies counting NGC 6500 group ( LGG 414 ).

The object was discovered together with NGC 6500 on June 29, 1799 by Wilhelm Herschel with an 18.7-inch reflector telescope, which was called “Two (NGC 6500 & NGC 6501) both vF, vS; place that of the following one, preceding one about 4 ′ more south and 5 or 6 seconds preceding "noted.
