Quick Reference

The distance within which the tidal forces exerted by a planet are sufficient to disrupt a satellite or smaller body. For bodies in circular orbits with zero tensile strength and the same mean density as the primary, the Roche limit is 2.46 × (primary-body radius). In the case of the Earth–Moon system, the critical distance is 2.89 Earth radii (18 400 km).
