IC 10 is a dwarf galaxy visible in the constellation of Cassiopeia.
It is located in the middle of the northern Milky Way, and its view is partly disturbed. Initially classified as an object belonging to our Galaxy, around the 1930s the hypothesis was put forward that it was an extragalactic object. Edwin Hubble suggested that it could be an object just outside the Local Group, but the question was resolved only in 1996, when, following the discovery of Cepheid variables within it, its exact distance was established.

IC 10 is located at the same distance as the Triangulum Galaxy with respect to the Andromeda Galaxy: this may suggest that it is a galaxy belonging to the subgroup of the latter.

It is the only starburst galaxy within the Local Group; has a remarkable density of Wolf-Rayet stars, compared to the Magellanic Clouds (in this respect it can be said that it is smaller than the Small Magellanic Cloud, although its absolute magnitude is comparable to that of the latter). The high level of oxygen in the galaxy, compared to that of the Small Magellanic Cloud, suggests that star formation activity has continued for a longer period of time, and is still continuing at a reasonable rate, since over 50,000 stars are formed within it each year. Ionized hydrogen (H II regions) are very extensive, particularly towards the center.
