Editing Epimetheus (moon) (section)

== Interactions with rings ==
A [[Rings of Saturn#Janus/Epimetheus Ring|faint dust ring]] is present around the region occupied by the orbits of Epimetheus and Janus, as revealed by images taken in forward-scattered light by the [[Cassini–Huygens|''Cassini'' spacecraft]] in 2006. The ring has a radial extent of about 5000&nbsp;km.{{sfn|JPL/NASA: Moon-Made Rings}} Its source are particles blasted off their surfaces by meteoroid impacts, which then form a diffuse ring around their orbital paths.{{sfn|Williams et al. 2011}}{{sfn|JPL/NASA: Creating New Rings}}

Along with Janus, Epimetheus acts as a [[shepherd moon]], maintaining the sharp outer edge of the [[A Ring]] in a 7:6 [[orbital resonance]]. The effect is more obvious when the more massive Janus is on the resonant (inner) orbit.{{sfn|El Moutamid et al|2015}}
