Composition. What little atmosphere the Moon has consists of some unusual gases, including sodium and potassium, which are not found in the atmospheres of Earth, Mars, or Venus.
28 Φεβ 2022 · In the moon's atmosphere, there are only 100 molecules per cubic centimeter. In comparison, Earth's atmosphere at sea level has about 100 billion billion molecules per cubic centimeter.
At the Moon’s center is a dense, metallic core. This core is largely composed of iron and some nickel. The Moon’s core is relatively small (about 20% of its diameter) compared to other terrestrial worlds (like Earth) with cores measuring closer to 50% of their diameters.
11 Ιαν 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 ...
1 Ιαν 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 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.
The Moon has a very thin and tenuous atmosphere called an exosphere. It is not breathable. The Moon has no moons. The Moon has no rings. More than 105 robotic spacecraft have been launched to explore the Moon. It is the only celestial body beyond Earth – so far – visited by human beings.
