Web18 de set. de 2024 · Titan is the only known moon with an atmosphere because it is so unique. Titan is thought to have significant amounts of Oort cloud materials (particularly nitrogen), which would have been absent in sufficient quantities in Saturnian systems at the time of its formation. WebTitan's atmosphere is mostly nitrogen, while the moon is mostly helium and argon. The helium in the moon's atmosphere is easily lost, since it's so much lighter. Another big cause of atmospheric loss is the solar wind.
The “airless” Moon really does have an atmosphere, after all
WebWe know that the Moon has almost no atmosphere and only about one-sixth of Earth’s gravity. We even know that there is quite a bit of frozen water tucked away in craters near the Moon's poles. There is no wind or air on the Moon to help “erase” craters, so the surface is covered with the remains of old and new impacts.

Web26 de jul. de 2015 · If you want an Earth-like atmosphere with water and all that, stable over the billions of years, you may need a molten core for magnetosphere, high enough gravity, etc. which means you probably need something about 0.4 M ⊕ or larger, so a moon larger than Mars. At that point, it's not really a moon, but a double planet. Web17 de fev. de 2024 · Assume that your planet-moon system is actually a double planet system. Assume that both planets are the same size. Obviously if one of the identical planets has sufficient gravity and magnetic field to retain a dense atmosphere, the other identical planet will also have sufficient gravity and magnetic field to retain a dense … Web12 de abr. de 2013 · The moon's atmosphere may play a key role in a potential lunar water cycle, facilitating the transport of water molecules between polar and lower latitude areas.
