eponym=Robert J. Helberg Helberg is a lunar crater that is located just behind the western limb of the
Moon , on the far side from theEarth . Due tolibration this part of the surface is sometimes brought into view, and the crater is visible under suitable lighting conditions. However even under these circumstances the crater is viewed from the edge and not much detail can be seen.This crater is nearly attached to the east-northeastern rim of the Robertson crater. Within a crater diameter to the northwest lies Berkner crater, and further to the east is Bell crater.
This is an eroded crater formation which overlays 'Helberg C' along the east-northeastern side and 'Helberg H' to the southeast. The southern rim is somewhat uneven, with an area of intrusion to the southwest. The interior floor has the remains of a crater rim at the northern end. It is otherwise relatively featureless.

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 Helberg crater.
