Alver is a crater on Mercury. It has a diameter of 151.49 kilometers. Its name was adopted by the International Astronomical Union (IAU) on March 15, 2013. Alver is named for the Estonian poet Betti Alver.[1]
Alver is one of 110 peak ring basins on Mercury.[2] It lies in southern Utaridi Planitia.
On the western side of the peak ring is a dark spot of low reflectance material (LRM), closely associated with hollows.[3]
