But the solar wind will strip is away over millions of years, little by little; the magnetosphere works by redirecting the plasma of the solar wind, so that it doesn't hit the atmosphere head on. And there is zero doubt that the magnetosphere cannot protect at all against electromagnetic radiation; it's basic physics. It protects only against charged particles, such as the plasma which constitutes the solar wind. Where the magnetosphere does not protect against them you get polar auroras, but life on the surface is still safe. | |
| Sep 21, 2018 at 20:08 | comment | added | Harthag | See, I've seen comments and answers explaining exactly the opposite, indicating that the planet's mass is what retains the atmosphere, and that the magnetosphere provides negligible protection from atmospheric stripping, but that the main function of the magnetosphere is radiation protection. And this type of conflicting information is exactly why I asked this question. So, in my scenario, the atmosphere on the moon will be comparable to Earth, the magnetosphere will not. Can earth life survive on this moon? or will radiation from the planet or star kill it? | |
| Sep 21, 2018 at 19:40 | comment | added | AlexP | Earth's magnetosphere does not provide that much protection against "radiation"; moreover, there are places near the magnetic poles, for example the Labrador peninsula in Canada, where the magnetosphere protection against "radiation" is very very small, if any. ("Radiation" in scare quotes because the magnetosphere cannot protect against X-rays and gamma rays at all.) The overwhelming majority of radiation protection is due to the atmosphere. The importance of the magnetosphere consists in protecting the atmosphere against the solar wind. | |
