A [[planet]]'s or [[star]]'s '''Roche limit''' is the smallest distance a satellite (which is held together only by gravitational forces) can approach it without being desintegrated by tidal forces.

 According to the [[NASA]]/[[IPAC]] extragalactic database, ''for a satellite of negligible mass, zero tensile strength, and the same mean density as its primary, in a circular orbit around its primary, this critical distance is 2.44 times the radius of the primary. (For the Moon, whose density is lower than that of Earth, the Roche limit would be 2.9 Earth radii.)''<ref>[http://nedwww.ipac.caltech.edu/level5/Glossary/Glossary_R.html Caltech Astronomical Glossary]</ref>

 As the ''Roche lobe'' and the ''Roche sphere'', the Roche limit is named after the [[French]] physicist Édouard Albert Roche (1820 – 1883).
