IC 2574
IC 2574, also known as Coddington's Nebula, is a dwarf spiral galaxy[6] discovered by American astronomer Edwin Foster Coddington in 1898.[8][9] Located in Ursa Major, a constellation in the northern sky, it is an outlying member of the M81 Group. It is believed that 90% of its mass is in the form of dark matter.[10]
