Atmosphere of the Moon. The thin lunar atmosphere is visible on the Moon's surface at sunrise and sunset with the lunar horizon glow [1] and lunar twilight rays, like Earth's crepuscular rays. This Apollo 17 sketch depicts the glow and rays [2] among the general zodiacal light [3][4]. The atmosphere of the Moon is a very sparse layer of gases ...
The geology of the Moon (sometimes called selenology, although the latter term can refer more generally to "lunar science") is quite different from that of Earth. The Moon lacks a true atmosphere, and the absence of free oxygen and water eliminates erosion due to weather. Instead, the surface is eroded much more slowly through the bombardment ...
Internal structure of the Moon. Moon's internal structure. Olivine basalt collected by Apollo 15. Thermal state of the Moon at age 100 Ma. [1] Having a mean density of 3,346.4 kg/m 3, [2] the Moon is a differentiated body, being composed of a geochemically distinct crust, mantle, and planetary core. This structure is believed to have resulted ...
The NASA astronauts who became the first people to land on the moon's surface in the 1960s and 1970s also discovered a previously unknown lunar characteristic - it has an atmosphere, though quite ...
Vertical diagram of Titan's atmosphere. Titan is the only moon in the Solar System with an atmosphere denser than Earth's, with a surface pressure of 1.448 atm, [52]: 834 and it is one of only two moons whose atmospheres are able to support clouds, hazes, and weather—the other being Neptune's moon Triton.
The thin lunar atmosphere is visible on the Moon's surface at sunrise and sunset with the lunar horizon glow [90] and lunar twilight rays, like Earth's crepuscular rays. This Apollo 17 sketch depicts the glow and rays [ 91 ] among the general zodiacal light .
The atmosphere of Titan is the dense layer of gases surrounding Titan, the largest moon of Saturn. Titan is the only natural satellite in the Solar System with an atmosphere that is denser than the atmosphere of Earth and is one of two moons with an atmosphere significant enough to drive weather (the other being the atmosphere of Triton ).

The Lunar Atmospheric Composition Experiment ( LACE) was a miniature magnetic deflection mass spectrometer (neutral mass spectrometer). The experiment's aim was to study the composition and variations of the lunar atmosphere. The only deployment of LACE was as part of the Apollo Lunar Surface Experiments Package (ALSEP) on Apollo 17 within the ...
