NGC 6500 is a spiral galaxy with an active nucleus of the Hubble type Sab in the constellation Hercules in the northern sky . It is an estimated 141 million light years away from the Milky Way and about 90,000 light years in diameter . Together with NGC 6501 , it forms the isolated, gravitationally bound galaxy pair KPG 526 .
It is the brightest member of the six-galaxy NGC 6500 group ( LGG 414 ).
The object was discovered in 1799 by the astronomer William Herschel with the help of his 18.7-inch reflector telescope and was later added to his New General Catalog by Johan Dreyer .
