What Makes Up the Solar System?
... Astronomers generally divide the planets into two groups, the inner and outer planets. The inner planets – Mercury, Venus, Earth, Mars – are rocky and are usually much smaller than the outer planets. The gas giants – Jupiter, Saturn, Uranus, and Neptune – are not as dense as the inner planets. They ...
