Mons Gruithuisen Gamma (γ) is a lunar dome[1] that lies to the north of the crater Gruithuisen at the western edge of the Mare Imbrium.
This massif is shaped as a rounded dome in the surface, occupying a diameter of 20 km and climbing gently to a height of over 1500 meters.[2][3] At the crest is a small crater.
This formation appears foreshortened when viewed from the Earth, and it has been described by Antonin Rukl as resembling an "upturned bathtub".[4]
To the east lies the similar Mons Gruithuisen Delta (δ). Together they are often informally called the Gruithuisen domes. To the south of the Gruithuisen domes is a portion of Oceanus Procellarum that was named Sinus Viscositatis by the IAU in December 2022.[5]
Mons Gruithuisen Gamma is the landing site for Peregrine Mission One, scheduled for January 2024.
