Jupiter by Cassini-Huygens.jpg
A composite Cassini image of Jupiter. The dark spot is the shadow of Europa. The Great Red Spot, a persistent anticyclonic storm, is at lower right. White atmospheric bands, termed zones, represent areas of upwelling; reddish bands, called belts, represent areas of downwelling. They display high-altitude ammonia ice clouds and lower clouds of unknown composition, respectively.

  6. Orbital elements refer to the barycenter of the Jupiter system, and are the instantaneous osculating values at the precise J2000 epoch. Barycenter quantities are given because, in contrast to the planetary centre, they do not experience appreciable changes on a day-to-day basis due to the motion of the moons.
