Figure 7-1 Jupiter and Its Vital Statistics This view was sent back from Voyager 1 in 1979. Features as small as 600 km (370 mi) across can be seen in the turbulent cloud tops of this giant planet. The complex cloud motions that surround the Great Red Spot are clearly visible. Also, clouds at different latitudes have different rotation rates. The inset image of Earth shows its size relative to Jupiter.
