Unformatted text preview: G i a n t P l a n e t s Mass, radius, rotation rate and atmosphere are significantly larger than Earths. Overall compositions similar to Suns except that heavy elements are 510 times more abundant: 6070% H, 2530% He, 515% C, N, O, Si, S, Fe, etc. Gaseous envelope and atmosphere, metallic H interior, ice and rock core. Surface temperatures around 100 K; Core temperatures above 10,000 K Violent winds correlate with observed belts and zones. Long-lived storm systems ( e.g. , Great Red Spot) are common. Produced by heat rising from below by convection. Leakage of more internal heat than gained from solar heating. Jupiter has intense magnetic field, probably due to large interior region of metallic H. Violent winds and lack of a solid surface make possibility of life bleak.
