c. 1990 — The Clementine topographic data use 1,737,400 meters as the baseline, and show a range of about 18,100 meters from lowest to highest point on the Moon. This is not a list of the highest places on the Moon, meaning those farthest from the CoM. Rather, it is a list of peaks at various heights relative to the relevant datum.
Geological studies of the Moon are based on a combination of Earth-based telescope observations, measurements from orbiting spacecraft, lunar samples, and geophysical data. . Six locations were sampled directly during the crewed Apollo program landings from 1969 to 1972, which returned 382 kilograms (842 lb) of lunar rock and lunar soil to Earth [8] In addition, three robotic Soviet Luna ...
A full moon sinking behind San Gorgonio Mountain, California, on a midsummer morning. Moonrise and moonset are times when the upper limb of the Moon appears above the horizon and disappears below it, respectively. The exact times depend on the lunar phase and declination, as well as the observer's location.
At this location the selenographic colongitude at sunrise is defined as 0°. Thus, by the time of the Full Moon the colongitude increases to 90°; at Last Quarter it is 180°, and at the New Moon the colongitude reaches 270°. Note that the Moon is nearly invisible from the Earth at New Moon phase except during a solar eclipse.

The ages of the mare basalts have been determined both by direct radiometric dating and by the technique of crater counting.The radiometric ages range from about 3.16 to 4.2 billion years old (Ga), [4] whereas the youngest ages determined from crater counting are about 1.2 Ga. [5] Updated measurements of samples collected by the Chang’e-5 mission show that some lunar basalts could be as ...
It's thought to have a higher silica content, making it thicker, slower moving and faster cooling, enabling it to pile up into these structures. Such silicic volcanism is rare on the Moon, and it's still unclear how it can occur there at all, as on Earth it requires the presence of water and plate tectonics - factors absent on the Moon. [6]
