Discovered 1899 by Delisle Stewart.

This object was discovered in September 1899 by Delisle Steward according to Pickering (1908). IC 5152 is a relatively nearby dwarf galaxy, either another outlying member galaxy of the Local Group, or just beyond the outlayers of our group of galaxies. In the latter case, it lies in the almost empty space between the Local Group and the Sculptor Group of Galaxies. It was first considered a Local Group member candidate by Yahil et.al. (1977). Previous distance estimates had positioned it at a distance of about 2 or 3 million light-years, well within the Local Group, but more recent and presumably more acurate detreminations have put it out to 5.8 million light-years, to or beyond the fringes of the Group. This dwarf irregular galaxy is receding from us at only 30 km/s, an argument for a possible group membership..
