 In the distant future these moons will impact the planet or penetrate deeply enough within their Roche limit to be tidally disrupted into fragments.The moons so affected are Metis and Adrastea at Jupiter, and the majority of the inner moons of Uranus and Neptune − out to and including Perdita and Larissa, respectively.However, none of Saturn's moons experience this effect because Saturn is a relatively very fast rotator.
