NGC 4725 is an intermediate barred spiral galaxy about 40 million light-years away in the constellation Coma Berenices. NGC 4725 is a Seyfert Galaxy, suggesting an active galactic nucleus containing a supermassive black hole.

NGC 4747 shows large Tidal Streams, probably caused by interaction with NGC 4725
