2.3.1 spase://CNES/NumericalData/CDPP-AMDA/Ephemerides/amalthea-orb-all Amalthea 2018-10-14T11:46:29Z Amalthea orbits Jupiter at a distance of 181 000 km (2.54 Jupiter radii). The orbit of Amalthea has an eccentricity of 0.003 and an inclination of 0.37° relative to the equator of Jupiter. 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 satellite, Io: in the past Amalthea has passed through several 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). Amalthea's orbit lies near the outer edge of the Amalthea Gossamer Ring, which is composed of the dust ejected from the satellite. spase://CNES/Person/NAIF PrincipalInvestigator jup-moons-orb PartOf Jupiter Moons spase://SMWG/Repository/CNES/CDPP-AMDA Online Open http://amda.cdpp.eu Text.ASCII SPICE spase://CNES/Instrument/CDPP-AMDA/Ephemerides Ephemeris 1970-01-01T00:00:05Z 2036-12-31T23:40:04Z PT20M Jupiter Jupiter.Amalthea xyz_jsm amal_jup_jsm Rj Cartesian JSM TimeSeries 3 x 1 amal_jup_jsm(0) y 2 amal_jup_jsm(1) z 3 amal_jup_jsm(2) Positional xyz_jso amal_jup_jso Rj Cartesian JSO TimeSeries 3 x 1 amal_sat_jso(0) y 2 amal_jup_jso(1) z 3 amal_jup_jso(2) Positional xyz_IAU_jupiter amal_jup_xyz Rj Cartesian IAU_Jupiter TimeSeries 3 x 1 amal_jup_xyz(0) y 2 amal_jup_xyz(1) z 3 amal_jup_xyz(2) Positional distance amalthea-jupiter amal_jup_r Rj TimeSeries Positional latitude IAU_jupiter amal_jup_lat deg Positional longitude IAU_jupiter amal_jup_lon deg Positional mlat amal_jup_mlat mlat=10.31°xcos(196.61°-lon_iau_west)+lat_iau deg Positional
