The atmosphere of the Moon is a very sparse layer of gases surrounding the Moon. For most practical purposes, the Moon is considered to be surrounded by vacuum.
If the Earth–Moon system isn't engulfed by the enlarged Sun, the drag from the solar atmosphere can cause the orbit of the Moon to decay. Once the orbit of the Moon closes to a distance of 18,470 km (11,480 mi), it will cross Earth's Roche limit , meaning that tidal interaction with Earth would break apart the Moon, turning it into a ring ...
Diagram of how Europa's atmosphere is created by bombardment from ionized particles. The atmosphere of Europa can be categorized as thin and tenuous (often called an exosphere), primarily composed of oxygen and trace amounts of water vapor. [130] However, this quantity of oxygen is produced in a non-biological manner.
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 ...
As the Moon's fine surface layer, lunar regolith is picked up by even weak natural phenomena active at the Moon's surface, allowing it to be part of the Moon's scant atmosphere. It is easily disturbed and poses a significant hazard to exposed equipment and human health.
The wispy outermost layer of Earth's atmosphere extends much deeper into space than scientists realized -- deep enough that the moon orbits through it.Earth's geocorona is a sparse, little ...
Lunar horizon glow is a phenomenon in which dust particles in the Moon's thin atmosphere create a glow during lunar sunset. The Surveyor program provided the first data and photos of the phenomenon. Astronauts in lunar orbit observed it during the Apollo 15 and Apollo 17 missions.
Lunar nearside with major maria and craters labeled. 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.
