About this image

Arp 307 consists of the galaxy pair of NGC 2874 (left) and NGC 2872. Both galaxies were discovered by William Herschel in March 1784.

NGC 2874 is a 12.5 mag. barred spiral galaxy. NGC 2872 is a mag. 11.9 elliptical galaxy. They are in interaction and lie at a distance of about 110million ly.

The smaller, fainter and more distant NGC 2873 lies a little above the pair in this COAST image. It is a mag. 15.4 lenticular galaxy. It was discovered, just over seventy years after the brighter pair, by R. J. Mitchell (an assistant of Lord Rosse) in February 1857.
