Topography of the Moon. STL 3D model of the Moon with 10× elevation exaggeration rendered with data from the Lunar Orbiter Laser Altimeter of the Lunar Reconnaissance Orbiter. Selenography is the study of the surface and physical features of the Moon (also known as geography of the Moon, or selenodesy). [1]
3D rendering of a DEM of Tithonium Chasma on Mars. A digital elevation model (DEM) or digital surface model (DSM) is a 3D computer graphics representation of elevation data to represent terrain or overlaying objects, commonly of a planet, moon, or asteroid.
Location of Tycho as seen from the Northern Hemisphere 3D model of Tycho crater. Tycho (/ ˈ t aɪ k oʊ /) is a prominent lunar impact crater located in the southern lunar highlands, named after the Danish astronomer Tycho Brahe (1546–1601). [2] It is estimated to be 108 million years old. [3]

The Moon's surface has many craters, all of which were formed by impacts. The International Astronomical Union currently recognizes 9,137 craters, of which 1,675 have been dated. [ 1 ]
Lunar maria (singular mare) are large, dark, regions of the Moon. They do not contain any water, but are believed to have been formed from molten rock from the Moon's mantle coming out onto the surface of the Moon. This list also includes the one oceanus and the features known by the names lacus, palus and sinus.
The Apollo Lunar Module (LM / ˈ l ɛ m /), originally designated the Lunar Excursion Module (LEM), was the lunar lander spacecraft that was flown between lunar orbit and the Moon's surface during the United States' Apollo program. It was the first crewed spacecraft to operate exclusively in the airless vacuum of space, and remains the only ...
Across the Moon, the lunar terminator is visible, the borderline between the Moon's day and night; the lunar limb is the Moon's profile against the dark sky, top right in this picture. The lunar limb is the edge of the visible surface (disc) of the Moon as viewed from Earth . [ 1 ]
