Mons Rümker is an isolated volcanic formation that is located in the northwest part of the Moon's near side, at selenographic coordinates 40.8° N, 58.1° W. The feature forms a large, elevated mound in the northern part of the Oceanus Procellarum.[1] The mound has a diameter of 70 kilometres, and climbs to a maximum elevation of about 1,300 metres above the surrounding plain.[1] It was named after Karl L. C. Rümker.
Mons Rümker has a concentration of 22 lunar domes - rounded bulges across the top, some of which contain a small craterlet at the peak. These are wide, circular features with a gentle slope rising in elevation a few hundred meters to the midpoint.[1] Lunar domes are similar to shield volcanoes, and are the result of lava erupting from localized vents followed by relatively slow cooling.[2]
Mons Rümker is surrounded by a scarp that separates it from the adjacent mare. The plateau rises to an altitude of 900 m in the west, 1,100 m in the south and 650 m in the east. The surface of Mons Rümker is relatively uniform, with a strong spectroscopic signature of lunar mare material. The estimated volume of lava extruded to create this feature is 1,800 km3.
A young lava plain to the northeast from Mons Rümker, named Statio Tianchuan, was the landing site of the Chang'e 5 mission.[3]
