Jupiter named after the Roman King of the Gods.

The Great Red Spot is cyclone storm that has been raging for over 300 years. This storm is about two earth diameters wide. The atmosphere is hydrogen and helium, with different types of clouds at different levels which gives Jupiter the band of different colors. The wind blows at over 640 km/hr in these rotating bands.

The upper-level clouds temperature is – 145° C

Jupiter does not have a true solid surface. Its atmosphere simply gets denser with depth, turning to liquid metallic hydrogen and it does have a small core.
