Roche limit, in astronomy, the minimum distance to which a large satellite can approach its primary body without tidal forces overcoming the internal gravity holding the satellite together. If the satellite and the primary body are of similar composition, the theoretical limit is about 2 1/2 times the radius of the larger body. The rings of Saturn lie inside Saturn’s Roche limit and may be the debris of a demolished moon. The limit was first calculated by the French astronomer Édouard Roche (1820–83). Artificial satellites are too small to develop substantial tidal stresses.
