Object data of WLM

Object type: Dwarf galaxy (dwarf Irr)
Size: 12' x 4'
Magnitude: 11.0mag
Constellation: Cet
Distance: 3.0 Mio Ly
Notes: The irregular dwarf galaxy WLM was discovered in 1909 by Max Wolf and it was identified as a galaxy about 15 years later by Knut Lundmark and Philibert Jacques Melotte. The WLM galaxy is a member of the Local Group of Galaxies. It can be found inside the constellation Cetus in a distance of 3.0 million light-years. Being at the edge of the Local Group has protected WLM from interactions and mergers with other galaxies. Therefore this galaxy could be described as an astronomical “living fossil” as it seems to have developed without ever interacting with any other galaxy since it formed billions of years ago. It's "pristine" stellar population and state make it particularly useful for comparative studies.
