WebAug 1, 2024 · In the Wikipedia article you link the Roche limit is written as: d = R ( 2 ρ M ρ m) 1 / 3. but R is the radius of the primary and ρ M is the density of the primary, so you … 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 completely rigid satellite will maintain its shape until tidal forces break it apart. At the other extreme, a highly fluid satellite … See more • Roche lobe • Chandrasekhar limit • Hill sphere • Spaghettification (the extreme case of tidal distortion) • Black hole See more In 2024, it was discovered that the minor planet 50000 Quaoar has a planetary ring. The ring is at a distance over seven times the radius of Quaoar, more than double the Roche limit. The reason for this is not yet understood.

The key element in binary star evolution is the role of the Roche limit, which was first introduced in the three-body problem. It is known in the celestial mechanics literature as a zero-velocity surface, but we will treat it as the bounding equipotential for a self-gravitating star: (6) little bitty girl lyrics
