Editing Metis (moon) (section)

== Orbit and rotation ==
Metis is the innermost of Jupiter's four small [[inner satellites of Jupiter|inner moon]]s. It orbits Jupiter at a distance of ~128,000&nbsp;km (1.79 Jupiter radii) within Jupiter's [[Rings of Jupiter#Main ring|main ring]]. Metis's orbit has very small [[orbital eccentricity|eccentricity]] (~0.0002) and [[inclination]] (~ 0.06°) relative to the equator of Jupiter.{{sfn|Evans Porco et al.|2002}}{{sfn|Burns Simonelli et al.|2004}}

Due to [[tidal locking]], Metis rotates synchronously with its orbital period (about 7 hours), with its longest axis aligned towards Jupiter.{{sfn|Burns Simonelli et al.|2004}}{{sfn|Thomas Burns et al.|1998}} Jupiter casts a shadow on all of Metis for 68 minutes each Metian day.{{efn|name=calculated}}

Metis lies inside Jupiter's [[synchronous orbit]] radius (as does [[Adrastea (moon)|Adrastea]]), and as a result, [[tidal deceleration|tidal force]]s slowly cause its orbit to decay. If its density is similar to Amalthea's, Metis's orbit lies within the fluid [[Roche limit]]; however, because it has not broken up, it must lie outside its rigid Roche limit.{{sfn|Burns Simonelli et al.|2004}}
