NGC 3008 is a lenticular galaxy with an active galactic nucleus [3] in the constellation of Ursa Major,[4] discovered by William Parsons and his assistants.[5] It is about 40 thousand light years across, and with a recessional velocity of about 4,785 kilometers per second,[5] is at a distance of 240 million light-years from the Sun.[1]
It is a member of the NGC 2998 group, which also includes NGC 2998, NGC 3002, NGC 3005, NGC 3006, and a few others.[6] Among these galaxies, it has the lowest star formation rate, at 0.02 M☉ per year.[7]
