NGC 4731

NGC 4731 is a barred spiral galaxy located near the Virgo supercluster. To its celestial south lies NGC 4731A, a small irregular galaxy. Both galaxies feature high concentrations of neutral HI gas. It is theorized that its elongated arm structure could be related to gravitational interactions with a nearby galaxy, NGC 4967. It is a member of the NGC 4697 Group of galaxies, which is a member of the Virgo II Groups, a series of galaxies and galaxy clusters strung out from the southern edge of the Virgo Supercluster.

Virgo II Groups

The Virgo II Groups, or Virgo II Cloud, are a series of at least 100 galactic clusters and individual galaxies stretching approximately 30 megalight-years off the southern edge of the Virgo Supercluster. It is located approximately 55 ly (16.86 pc) to 80 ly (24.53 pc) from the Solar System, at a right ascension of 12h 00m to 13h 30m.
