Because it is situated in the Sculptor Group, it is one of the closest galaxies to the Milky Way. It is obscured by a few brighter stars and galaxies (the brightest of them on the right side of the photo is 1425 light-years away from the Solar System[4]).
The galaxy has a diameter of 2,000 light years.[5]
