  1. The Planets An overview of the Solar System

  2. The Sun • The sun is the biggest, brightest, and hottest object in the solar system. • The sun is an ordinary star. • The sun is made of about 70% hydrogen and 28% helium.

  3. Mercury • Mercury is solid and is covered with craters. • Mercury has almost no atmosphere. • Mercury is the eighth largest planet.

  4. Venus • Venus is the sixth largest planet. It’s about three-fourths the size of earth. • The surface is rocky and very hot. The atmosphere completely hides the surface and traps the heat.

  5. Earth • Earth is the fifth largest planet and the third from the sun. • Liquid covers 71 percent of the Earth’s surface. • The Earth has one moon.

  6. Mars • Mars is the fourth planet from the sun. • Mars has a thin atmosphere that contains mostly carbon dioxide. • Mars has two small moons.

  7. Jupiter’s Red Spot • The Great Red Spot, a huge storm of swirling gas that has lasted for hundreds of years. • Jupiter does not have a solid surface. The planet is a ball of liquid surrounded by gas.

  8. Moons of Jupiter Jupiter has four large Galilean moons, twelve smaller named moons and twenty-three more recently discovered but not named moons.

  9. Saturn • Saturn is the second largest planet and the sixth from the sun. • Saturn is made of materials that are lighter than water. If you could fit Saturn in a lake, it would float!

  10. Rings of Saturn • Saturn’s rings are not solid; they are composed of small countless particles. • The rings are very thin. Though they’re 250,000km or more in diameter, they’re less than one kilometer thick.

  11. Uranus • Uranus is the third largest planet and the seventh from the sun. • Uranus is one of the giant gas planets. • Uranus is blue-green because of the methane in its atmosphere.

  12. Neptune • Neptune is the fourth largest planet and the eight from the sun. • Because of the orbits, from 1979 to 1999, Neptune was the ninth planet. • Like Uranus, the methane gives Neptune its color.

  13. Pluto • Pluto is the smallest planet and usually the farthest from the sun. • Pluto is the only planet that has not been visited by a spacecraft.

  14. Asteroid Belt • Between Mars and Jupiter • Between 700,000 and 1.7 million asteroids

  15. Kuiper Belt • Outside Neptune • At least 70,000 objects • Short-period comets • Less than 200 year orbit

  16. Oort Cloud • Far beyond the orbit of Pluto • Long-period comets • More than 200 year orbit
