== Orbit == [[File:Jupiter Showcases Auroras, Hazes (NIRCam Widefield View - Annotated).png|240px|thumb|Amalthea (left) imaged by the [[James Webb Space Telescope]] (20 August 2022)]] [[File:Amalthea_by_Juno.png|thumb|"A distant image of Amalthea passing in front of Jupiter was captured by the Juno spacecraft on 7 March 2024 during its 59th Perijove."]] Amalthea orbits [[Jupiter]] at a distance of 181,000 km (2.54 [[Jupiter radius|Jupiter radii]]). The orbit of Amalthea has an [[orbital eccentricity|eccentricity]] of 0.003 and an [[inclination]] of 0.37Β° relative to the equator of Jupiter.{{sfn|Cooper Murray et al.|2006}} Such appreciably nonzero values of inclination and eccentricity, though still small, are unusual for an [[inner satellite]] and can be explained by the influence of the innermost [[Galilean satellites|Galilean satellite]], [[Io (moon)|Io]]: in the past Amalthea has passed through several [[orbital resonance|mean-motion resonances]] with Io that have excited its inclination and eccentricity (in a mean-motion resonance the ratio of orbital periods of two bodies is a rational number like ''m'':''n'').{{sfn|Burns Simonelli et al.|2004}} Amalthea's orbit lies near the outer edge of the [[Rings of Jupiter#Amalthea gossamer ring|Amalthea Gossamer Ring]], which is composed of dust ejected from the satellite.{{sfn|Burns Showalter et al.|1999}}
