Dwingeloo 2

Dwingeloo 2 is a small spiral galaxy and is a companion of Dwingeloo 1.

Dwingeloo 2 was first detected at radio wavelengths from the 21cm emission line of neutral atomic hydrogen (known to astronomers as HI) in the course of follow-up observations after the discovery of Dwingeloo 1.

Dwingeloo 1 and Dwingeloo 2 are thought to be members of a nearby group, the Maffei Group.
