Origin • Thebe is one of the four known small moons that orbit closer to Jupiter than the four vastly larger Galilean moons. • Thebe was discovered in 1980 by the Voyager science team from images taken by Voyager 1. • Thebe was one of Zeus’ lovers. Jupiter is the Roman equivalent of Zeus.
Characteristics • Its mass is 1.5x10^18 • However its diameter is small only 31 miles • Its escape velocity is also very low with 142mph • Thebe orbits within the outer edge of the Thebe Gossamer Ring that is formed from dust ejected from its surface.
Physical attributes • Thebe is irregularly shaped and reddish in color, and is thought like Amalthea to consist of porous water ice with unknown amounts of other materials. Its surface features include large craters and high mountains—some of them are comparable to the size of the moon itself.
