An illustration shows Jupiter at the center of the image with its four Galilean moons extending toward the left — Io, Europa, Ganymede, and Callisto, their orbits traced by ever-increasing ellipses. On the other side of the image, another arc, in blue and entering from the right side of the image, shows the Juno spacecraft's orbit around Jupiter.
