Overview

From Wikipedia, the free encyclopedia · Read full article · Text CC BY-SA 4.0

Aegaeon, or Saturn LIII, is a natural satellite of Saturn. It has an extremely elongated shape whose surface is thought to be similarly smooth as Methone. It orbits between Janus and Mimas within Saturn's G Ring, in a 7:6 orbital resonance with the latter. Compared to the similar moons Anthe and Methone, which are both in orbital resonances with Mimas, Aegaeon is more tightly trapped in its resonance than the other two. In addition, all three of the moons are associated with arc structures formed from material blasted off their surfaces, but Aegaeon is the smallest among the three while its arc is the brightest.
