Many of them were contained in compounds with oxygen. Outer planets are significantly larger than the inner planets, as Jupiter is measured 88846 miles across and Mercury is 3031 miles across. Outer planets are significantly larger than the inner planets, as Jupiter is measured 88846 miles across and Mercury is 3031 miles across. Outer planets have a larger number of moons, no fixed part; rotate faster, have a lower density, and in some cases rings (Jupiter and Saturn).
Only substances with very high melting points would have remained solid in the inner solar system. When the gases merged into a protosun, the temperature in the solar system rose.
How are the inner planets different from the outer planet quizlet?
Inner planets are smaller than the outer planets; gas giants have more gravity; further apart, inner planets have a solid surface, inner planets are hotter, inner planets have a shorter period of rotation.
