NGC 4485

Irregular galaxy in the constellation Canes Venatici

NGC 4485 is an irregular galaxy located in the northern constellation of Canes Venatici. It was discovered January 14, 1788 by William Herschel.[6] This galaxy is located at a distance of 29[4] million light years and is receding with a heliocentric radial velocity of 483 km/s.[4]

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]

  • NGC 4485 and NGC 4490.
  • Interaction between them created a stream of material about 25 000 light-years long.[8]
