Rocky planets and giant planets in the Solar System – basic principles
How it works
In the Solar System, a distinction is made between rocky planets (Mercury, Venus, Earth, Mars) and giant planets (Jupiter, Saturn, Uranus, Neptune). Rocky planets consist mainly of solid materials such as rock and metal, are relatively small, and are closer to the Sun. Giant planets consist predominantly of gases (Jupiter, Saturn: gas giants) or ice and gas (Uranus, Neptune: ice giants), are much larger and farther from the Sun. The differences concern structure, size, composition, number of moons, and the presence of rings.
Note
Rocky planets are small, solid planets near the Sun, whereas giant planets are large, mostly gaseous or icy, and farther away.
