The Ant 2 "ghost" galaxy is a large, dim dwarf galaxy that scientists have discovered near the edge of the Milky Way. While low in mass, Ant 2 is about the same size as the Large Magellanic Cloud (LMC). (Credit: V. Belokurov and A.

A moderately eroded fluvial sinuous ridge (FSR), with lots of small craters in it, that stands out clearly above the surrounding material. To the north east it emerges from a small valley and becomes progressively clearer to the west, until it disappears. There is a clear curve in the FSR, likely a meander. North of the FSR is a round, flat feature that was likely an impact crater which was filled with water or sediment.
