What is the Solar System? The Solar System is a “group” of 8 planets, one son, and with multiple planets having natural satellites (moons).
Inner/Outer Planets There are Inner and Outer Planets. The Inner Planets are closest to the sun, and on the sun side of the asteroid belt. The Outer Planets are on the other side of the asteroid belt, and are farther from the sun, and are MUCH colder. Inner Planets are made of more of a rocky material, while outer planets have many more moons, and are made of gases and ices.
Jupiter Jupiter is the largest planet in the Solar System, and is made of gases. Jupiter has 63 known natural satellites (moons).
Saturn Saturn, the second largest planet in the solar system, has 62 confirmed satellites. It also has a relatively large system of rings.
Uranus Uranus is the second-farthest planet from the sun, and has 27 known natural satellites.
Neptune Neptune is the farthest planet away from the sun, and has 13 moons.
Dwarf Planet: Pluto As of 2006, Pluto, which used to be the ninth and smallest planet of the Solar System, was changed to the newly created definition, Dwarf Planet (because of its small size, being .6% of earth’s size).
