Galaxy group information
NGC 6221 is part of galaxy group NGC 6221/15, which includes spiral galaxy NGC 6215 and three dwarf galaxies. Interactions between NGC 6221 and NGC 6215 form a double-stranded bridge of neutral hydrogen gas over a projected distance of 100 kpc; Dwarf 3 of the three dwarf galaxies may have formed from the bridging gas.
