Jupiter has 79 moons that orbit the planet, the largest of which is Ganymede. Ganymede is larger than the planet Mercury and has its own magnetic field. Several spacecraft have flown by this moon including both Voyageur missions, the Galileo spacecraft, and Juno which is currently in orbit around Jupiter.
This image taken by Juno show the storms of Jupiter, some of which are being eclipsed by the moon Ganymede. The dark circle is the shadow of the moon. It is possible to see both the prenumbral (outer) and umbral (inner) shadows in this image. Image credit: NASA
