Its orbit has an eccentricity of 0.018, and an inclination of 1.08° relative to the equator of Jupiter.[3] These values are unusually high for an inner satellite and can be explained by the past influence of the innermost Galilean satellite, Io;[5] in the past, several mean-motion resonances with Io would have passed through Thebe's orbit as Io gradually receded from Jupiter, and these excited Thebe's orbit.[5]
