Mons Esam is a small, isolated mount on the northern part of the Mare Tranquillitatis. It is located to the southeast of the crater Vitruvius, and to the west-northwest of Lyell. To the northeast of this ridge is the bay called Sinus Amoris.
The selenographic coordinate of this feature is 14.6° N, 35.7° E, and it has a maximum diameter at the base of 8 km. The name of this feature is an Arabic masculine name (عصام), and it was not chosen to represent a specific individual. This peak is a lunar cone that was formed through tectonic processes.
A pair of tiny craters just to the south of Mons Esam have been assigned names by the IAU. These are listed in the table below.
