For bodies sufficiently large to be pulled to a sphere by their own gravity (like planets), the Roche limit determines where tides are strong enough to start ripping things apart. The Roche limit can be determined entirely by the densities of the two bodies and the radius of the larger body; the radius of the smaller body doesn't directly come into the equation. en.wikipedia.org/wiki/Roche_limit | |
