Earth roche limit
WebThe Roche limit is an estimated distance from a planet or object in a solar system beyond which the gravitational force of the larger body isn’t typically strong enough to prevent the gravity of ... In celestial mechanics, the Roche limit, also called Roche radius, is the distance from a celestial body within which a second celestial body, held together only by its own force of gravity, will disintegrate because the first body's tidal forces exceed the second body's self-gravitation. Inside the Roche … See more The Roche limit typically applies to a satellite's disintegrating due to tidal forces induced by its primary, the body around which it orbits. Parts of the satellite that are closer to the primary are attracted more strongly by gravity … See more The limiting distance to which a satellite can approach without breaking up depends on the rigidity of the satellite. At one extreme, a … See more • Roche lobe • Chandrasekhar limit • Hill sphere • Spaghettification (the extreme case of tidal distortion) See more In 2024, it was discovered that the minor planet 50000 Quaoar has a planetary ring.

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.
