Where is the Roche limit most famously visible in the Solar System?

The Roche limit is a gravitational boundary best illustrated by Saturn’s rings, where particles remain spread out rather than forming a moon. It describes the distance from a planet within which a smaller body held together only by its own gravity can be disrupted by tidal forces. The concept is named after Édouard Roche, who developed it in the 19th century. Similar physics also helps explain why some comets break apart when they pass too close to the Sun or a planet.
