WebApr 12, 2024 · One should distinguish the "Roche limit" from the "Roche lobe," as the latter is what you need when you have two objects of similar mass, like a binary star. The Roche lobe is an effective equipotential in a frame that cororates with the orbit of the binary (assumed circular). The equipotential is "effective" because it includes both stellar ... WebFeb 8, 2024 · The meaning of ROCHE LIMIT is the distance from a planet's center within which a satellite can neither approach nor reside without being disrupted by tidal forces. …

WebDec 15, 2011 · The Roche limit, as Tiscareno defines it, "is the distance from a planet within which its tides can pull apart a compact object....However, the Roche limit does not actually have a single value, but depends particularly on the density and internal material strength of the moon that may or may not get pulled apart." WebJul 15, 2014 · A short visualisation of the Roche limit: watch the black planet rip the gray moon apart with tidal forces, creating a ring system. survivors from the titanic names
Roche lobe - Wikipedia
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 limit, orbiting … 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 … 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 See more • Discussion of the Roche Limit • Audio: Cain/Gay – Astronomy Cast Tidal Forces Across the Universe – August 2007. • Roche Limit Description from NASA 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.
