De Vaucouleurs Atlas Description:

This nearby Local Group irregular shows only incipient resolution on the Atlas image, obtained with the CTIO Curtis Schmidt telescope. The structure looks unusual and may be affected by both Galactic and internal extinction. Karachentsev (2005) lists IC 10 as a member of the Andromeda subgroup of the Local Group at distance of 660 kpc. The absolute magnitude is MB = -15.6.

IC 10 is well-studied because it is the nearest starburst galaxy (Crowther et al. 2003). The galaxy's high H-alpha, near-IR, and radio continuum luminosities, and also its large number of massive stars, point to a recent starburst . Richer et al. (2001) conclude that IC 10 has properties in common with blue compact dwarf galaxies , and is therefore the nearest example of such an object.
