Roche limits
WebThe Roche limit of the Earth is 9500km, but I believe that's measured from the centre of the earth, whose radius is 6350km. So if the asteroid holds together up to the Roche limit, it only has 3150km to impact, not 9500km. That's only 158s at 20km/s. WebIn 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 …

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 can rewrite the equation as: d = ( 2 ρ M R 3 ρ m) 1 / 3 = ( 2 3 M 4 π ρ m) 1 / 3. where M is the mass of the primary. This allows you to calculate the Roche limit for ... WebThe Roche limit is also usually calculated for the case of a circular orbit, although it is straightforward to modify the calculation to apply to the case (for example) of a body passing the primary on a parabolic or hyperbolic trajectory. The rigid-body Roche limit is a simplified calculation for a spherical satellite.

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 ... spam chroniclesWebThe Roche limit is a distance, the minimum distance that a smaller object (e.g. a moon) can exist, as a body held together by its self-gravity, as it orbits a more massive body (e.g. its parent ... spam christmas ornamentWebSep 18, 2024 · $\begingroup$ If the Earth were to spiral into the towards the Roche limit, first the tides would increase in size, alternately flooding and then draining land.
