Dwingeloo 1 is a barred spiral galaxy about 10 million light-years away from the Earth,[3] in the constellation Cassiopeia. It lies in the Zone of Avoidance and is heavily obscured by the Milky Way. The size and mass of Dwingeloo 1 are comparable to those of Triangulum Galaxy.

Dwingeloo 1 has two smaller satellite galaxies – Dwingeloo 2 and MB 3 – and is a member of the IC 342/Maffei Group of galaxies.
