Thebe (thee'-bee, IPA ; Greek Θήβη) is the fourth of Jupiter's known moons by distance from the planet. It was discovered by Voyager 1 on March 5, 1979 and was first given the temporary name S/1979 J 2. Later, it was found on images dating back to February 27, 1979. In 1983 it was officially named after the mythological nymph Thebe who was the daughter of the river god Asopus. It is also designated Jupiter XIV.
It is the outermost of the inner Jovian moons (the "Amalthea group").
There appear to be at least three or four very large impact craters on the satellite (very large in the sense that each of these craters is roughly comparable in size to the radius of Thebe). Little else is known about it.
