Discuss why the inner planets are rocky, and the outer planets are gaseous. If the Sun was substantially hotter than it is today would the range of gaseous planets in general be positioned further away from the sun then they are today? Discuss why or why not? Why is Pluto no longer considered a Planet?
Any assistance with questions would be helpful. I don't understand if planets would ever move depending on temperature because if that were the case, wouldn't they have already moved since the sun is continually increasing in temperature according to all the fuss about global warming?
