Stephan's Quintet This grouping of galaxies is located in the constellation Pegasus, about 280 million light-years from the Solar System. It was the first such compact group discovered and is also called Hickson Compact Group 92. 4 galaxies are physically connected and interacting: NGC 7318 A and B, NGC7319, and NGC7317 (and possibly NGC7320c). The brightest member of the group, NGC7320 is actually in the foreground closer to the Solar System. This galaxy is visually part of the Stephan's Quintet group, but is physically much closer to the Solar System than the main group. It is 40 million years from the Solar System.
