'''Adrastea''' is the second known natural satellite of [[Jupiter]] by distance and the smallest inner moon. Discovered by photos from [[Voyager 2]] in 1979, it became the first moon discovered by an interplanetary spacecraft, rather than from [[Earth]].<br>

Adrastea is one of the few moons in the [[Solar System]] that orbits its planet in less than one of the planet's days. Located at the edge of Jupiter's main ring, it is thought that it contributes material to that ring.
