NGC 4485 is interacting with the spiral galaxy NGC 4490 and as a result both galaxies are distorted and are undergoing intense star formation. They have a projected separation of 9.3 kpc and are surrounded by an extended hydrogen envelope with a dense bridge of gas joining the two. Both galaxies are otherwise isolated and of low mass. The star formation rate in NGC 4485 is 0.22 M☉·yr−1.[7]
