IC 1101 is the central cD galaxy of the galaxy cluster Abell 2029 . It is one of the largest known galaxies . It is located in the constellation Virgo , right on the border with Serpens , at a distance of about a billion light years. Its effective radius is given as 42 arc seconds, corresponding to about 50 kpc (150,000 light years). It is surrounded by a diffuse halo that can be traced from the galaxy for up to 300 arc seconds, i.e. has a diameter of about 900 kpc. However, this halo is not assigned to the galaxy itself, but rather to the galaxy cluster as a so-called intra-cluster light .
The object was discovered on June 19, 1890 by Edward D. Swift .
