Balmer is the lava-flooded remains of a lunar crater. Only the heavily-worn southern and eastern sections of the crater still survive; the remainder being overlaid by lava-flow that joins to the nearby maria. Balmer crater lies to the east-southeast of Vendelinus crater.

By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Balmer crater.
