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. [1]

Roche limit, in astronomy, the minimum distance to which a large satellite can approach its primary body without tidal forces overcoming the internal gravity holding the satellite together.

2014年10月27日 · The Roche limit was created to study Saturn’s rings, but it’s now useful in understanding the thousands of exoplanets being discovered by space telescopes.

2023年12月26日 · The Roche limit, also called Roche radius, refers to the distance within which a celestial object, such as a planet or moon, will be destroyed by tidal forces due to the gravitational pull of a larger object, such as a star.

2024年4月7日 · The Roche Limit is a concept in astronomy that refers to the minimum distance at which a celestial body, such as a moon or a planet, can approach another celestial body without being torn apart by tidal forces.

The Roche limit is the point at which the tidal effects of a large body on a smaller one become powerful enough to overcome that second body’s own internal gravity, causing it to …

2023年1月1日 · The Roche limit is the orbital distance below which a satellite is tidally destroyed by the body around which it is orbiting. Édouard Roche is the French astronomer who first calculated this theoretical limit in 1848.

The Roche Limit

2005年10月21日 · Roche Limit Suppose a satellite is orbiting a planet – for example the Moon (mass m) orbiting the Earth (mass M) separated by distance d. There is a limit to how close the the satellite can approach the planet without having the satellite breaking up due to tidal forces. The assumption is that astronomical bodies are held together by self ...

The Roche limit, sometimes referred to as the Roche radius, is the distance within which a celestial body held together only by its own gravity will disintegrate due to a second celestial body's tidal forces exceeding the first body's gravitational self-attraction.
