WebAug 24, 2005 · Clearly, none of the moon can contact the roughly 65 miles above Earth that includes the atmosphere, and given its size that puts a bare minimum at about 700 miles, but I suspect that it would still be a huge problem that close, and it has to be stable. But, a fairly close orbit could be stable with the right momentum. WebOct 17, 2024 · If the Moon comes any closer than the Roche limit, it will break apart because of tidal forces. Thus no planet can have a moon that lies within the Roche limit – it can have only rings. The size of the Roche limit depends on the mass of the two bodies. For the Earth-Moon system, the Roche limit is about 6000 miles, center to center.
WebMay 15, 2024 · The Roche limit is a limit on objects being held together by their own gravity. Satellites are held together by much stronger forces. Different parts of the satellite are ultimately connected by chemical bonds, which are electromagnetic.
