| Eponym | David Gill |
Gill is a lunar crater that is located near the southeastern limb of the Moon. Due to its proximity to the edge of the Moon as seen from the Earth, this crater is viewed nearly from the side and it can become hidden from sight due to libration. The crater lies to the southwest of the irregular Mare Australe, and southeast of the prominent Pontécoulant crater. To the southwest of Gill is the Helmholtz crater.
This is an old, eroded crater formation with an outer rim that is uneven from a history of impacts. A joined pair of small craters lie along the northern rim, and 'Gill A' intrudes slightly into the western outer rim. The interior floor is relatively level, and is marked by several small and tiny craterlets.
Satellite craters
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 Gill crater.
