The Solar System includes four terrestrial planets (composed of rock and metal) and four gas giants (gaseous material). The four terrestrial planets are Mercury, Venus, Earth, and Mars, and the four gas giants are Jupiter, Saturn, Uranus, and Neptune. These names are derived from Roman gods and goddesses.
