B3 1715+425 is a small radio galaxy or blazar located in the constellation of Hercules, within the galaxy cluster ZwCl 8193, approximately 2.35 billion light-years from Earth. It is known as a potential candidate of a hypercompact stellar system; as well as an ultracompact dwarf galaxy. Its mass is around ~6 billion solar masses, concentrated in a region about 450 pc (1,500 light years) in radius. It is about 8.5 kiloparsecs (28,000 light years) away from the nucleus of its primary brightest cluster galaxy and is moving away from it at the speed of 4 500 000 miles an hour (7 200 000 kilometres per hour, 2,000 kilometres per second; ~0.68% the speed of light); such that it is stripping behind gases. It is theorized that it might be a larger galaxy in the past and was absorbed by its parent galaxy at its perinigricon.
