Thebe was a nymph and the daughter of the river god Asopus. Thebe rotates synchronously around Jupiter. Very little is known about this moon. These two images of the Jovian moon Thebe were taken by Galileo's solid state imaging system in November 1996 and June 1997, respectively.
North is approximately up in both cases.
In such a tidally locked state, one side of Thebe always points in the direction in which Thebe moves as it orbits about Jupiter. It was taken by the Voyager 1 spacecraft 4 hours 26 minutes before the closest approach to Jupiter. The dark circular disk is the shadow of Thebe and not the actual planet. Once the shadow images were analyzed, Thebe was located on several other images. Thebe is the small dark dot above the arrow.
