Webstar (Roche 1849). This is the familiar form of the Roche limit. In cases where the orbital period P of the planet is mea-sured directly it is more useful to rewrite the equation using Kepler’s third law, (2π/P)2 = GM/a3. The stellar mass and radius cancel out, giving Pmin ≃ s 3π (2.44)3 Gρp ≃12.6 hr ρp 1 g cm−3 −1/2, (2) WebJan 25, 2024 · As a concrete astrophysical example we obtain the expression of the Roche limit (the orbital distance at which a satellite begins to be tidally torn apart by the body it orbits) in the Weyl type gravity.

Roche himself derived the following approximate solution for the Roche limit: d ≈ 2.44 R ( ρ M ρ m ) 1 / 3 {\displaystyle d\approx 2.44R\left({\frac {\rho _{M}}{\rho _{m}}}\right)^{1/3}} However, a better approximation that takes into account the primary's oblateness and the satellite's mass is: See more 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 … See more The limiting distance to which a satellite can approach without breaking up depends on the rigidity of the satellite.
