This is an interacting galaxy pair located 37 arcminutes northeast of the 4th-magnitude 109 Virginis, the easternmost star of the constellation Virgo. On the right is NGC 5774, with a size of approximately 3 arcminutes. It is classified as a type of dwarf galaxy known as a low-surface-brightness (LSB) galaxy, with several dotted structures arranged along its faint arms. On the left is the edge-on galaxy NGC 5775, which has a major axis of just over 4 arcminutes. Although unclear in this image, a bridge-like structure connecting the two galaxies is visible, indicating that stars and interstellar matter are known to be moving from NGC 5774 to NGC 5775. This galaxy pair is located approximately 70 million light-years away and is part of a galaxy group belonging to the Virgo III Galaxy Cluster.
Additionally, the two galaxies appearing at the lower right of the image are IC 1066 below and IC 1067 above.
