Robert's Quartet is a compact galaxy group approximately 160 million light-years away in the constellation Phoenix.
It is a family of four very different galaxies whose proximity to each other has caused the creation of about 200 star-forming regions and pulled out a stream of gas and dust 100,000 light years long.
[1] Because such groups contain four to eight galaxies in a very small region they are excellent laboratories for the study of galactic interactions and their effects, in particular on the formation of stars.
[3] The brightest member of the group is NGC 92, having the blue magnitude of 13.8.
[3] It was named by Halton Arp and Barry F. Madore, who compiled A Catalogue of Southern Peculiar Galaxies and Associations in 1987.
