Planets
Our Solar System Planets:
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto
Terrestrial Planets
Mercury, Venus, Earth, and Mars are terrestrial planets. They all are smaller than the other planets with rocky surfaces. These planets tend to be denser. The word terrestrial has Latin roots, as terra means "Earth." All of the terrestrial planets have around zero to two moons, and are all less than 1.5 AU's from the sun.
Gas Giants
Jupiter, Saturn, Uranus, and Neptune are the four outer planets, as well as the gas giants. They are much more massive than Earth and their surfaces are not solid. They have atmospheres mostly made up of hydrogen and helium. The outermost planets have a stronger gravitational force due to their size. They all have extremely thick atmospheres. The outside layers of the gas giants are cold, but get tremendously hotter as you go into the planet. Each gas giant has a set of rings, or a disk of small particles composed of ice and rock.
