Grainger is a crater on Mercury. Its name was adopted by the International Astronomical Union (IAU) in 2012, after the Australian-born composer George Percy Aldridge Grainger.[1]
Grainger has a rather prominent central peak, which rises above much of the rim of the crater.[2] There is slumping evident around much of the outer rim.
There are irregular depressions with a halo of high-albedo material in the northeast quadrant of the crater, which may be volcanic in nature.[3]
The large Rembrandt basin is to the northwest of Grainger, and to the northeast is Beckett crater.
