Irregular Galaxy IC 1613

About this object

IC 1613 is an irregular dwarf galaxy in Cetus, near the star 26 Cet. It similar to, but much smaller and less luminous than, the Magellanic Clouds.
This object was discovered by Max Wolf in 1906. J. L. E. Dreyer describes it in the Index Catalog as "faint and extremely large". IC 1613 has a visual magnitude of 9.2, and apparent dimensions of 20.0' x 18.5'.
IC 1613 was one of the first galaxies to be recognized as a member of the Local Group (by Walter Baade in 1928) because it could be resolved into individual stars. Baade estimated it to be at a distance comparable to that of NGC 6822. IC 1613 is about 2.8 million light-years away. It has a total luminosity of about 130 million suns, and a diameter of 16,000 light-years. It is approaching us at 234 km/sec.
