Galaxy group information
NGC 6215 is part of galaxy group NGC 6221/15, which includes barred spiral galaxy NGC 6221 and three dwarf galaxies. A double-stranded bridge of neutral hydrogen gas connects NGC 6215 and 6221 as a result of their interaction, and Dwarf 3 of the three dwarf galaxies may have formed from the bridging gas.[4]
