I have to write a paper on the Jovian Planet System
Astronomers claim to have a reasonable model for interior structure of Jupiter. What is the observational basis for this model? Does it make any predictions that have been put to observational tests? How is the interior structure of the Earth known (review Chapter 7 if necessary)? Do you think the interior structure of Jupiter is more or less well-tested than that of the interior structure of the Earth? Explain.
