Cupid is doomed: An analysis of the stability of the inner uranian satellites

► We simulated the orbits of the inner uranian satellites using various assumptions. ► These satellites are unstable and cross orbits in 103-107 years. ► Cupid and Belinda cross orbits first, followed by Cressida and Desdemona. ► Crossing times exhibit large variation with initial conditions. ► We develop a new power law to handle multiple unstable moon subsets.
