The jovian planets (Jupiter, Saturn, Uranus, and Neptune) are more similar to the Sun in composition because they are primarily made up of hydrogen and helium, just like the Sun. The terrestrial planets (Mercury, Venus, Earth, and Mars), on the other hand, have compositions dominated by heavier elements.
