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.
11 sty 2024 · Diurnal temperature range (equator): 95 K to 390 K (~ -290 F to +240 F) Total mass of atmosphere: ~25,000 kg Surface pressure (night): 3 x 10-15 bar (2 x 10-12 torr) Abundance at surface: 2 x 10 5 particles/cm 3 Estimated Composition (night, particles per cubic cm): Helium 4 (4 He) - 40,000 ; Neon 20 (20 Ne) - 40,000 ; Hydrogen (H 2) - 35,000 ...
28 lut 2022 · One of the sources for the moon's atmosphere is outgassing, the release of gases from the lunar interior, usually due to radioactive decay. Outgassing events may also occur during moonquakes .
4 lut 2016 · When the moon is overhead, its gravity causes Earth’s atmosphere to bulge toward it, so the pressure or weight of the atmosphere on that side of the planet goes up. I am interested in understanding the Physics behind that increase in pressure.
Moon by astronauts detected a very low atmospheric pressure. As summarized recently in a comprehensive review of lunar atmospheric science by Stern (1999), the Apollo instruments measured a concentration of gases of approximately 107 particles/cm3 during the day and about 105 particles/cm3 at night. Such densities
1 sty 2023 · The Moon’s atmosphere is extremely tenuous: its molecules rarely collide with each other, instead travel ballistically from place to place, and only collide with the surface or are lost to space. Such an atmosphere is called a surface-bounded exosphere.
The possible existence of a lunar atmosphere has both fascinated and challenged astronomers for hundreds of years. Galileo searched for evidence of clouds, and Kepler imagined an Earth-like climate. Landings during the Apollo era brought instruments that measured a weak atmospheric pressure.
