IC 2574 is a dwarf spiral galaxy in Ursa Major. Known as Coddington's Nebula, it is part of the M81 group of galaxies. It is believed that dark matter accounts for up to 90% of it's mass. At 50,000 light years across, it is less than 1/2 the size of the Milky Way, but it is relatively close at 12 million light years, so it maintains a respectable apparent size in our sky.
