2. SWhat is the Solar System?s a olar System? The Solar System began 5 billion years ago. There were 9 planets, but scientists think Pluto should not be considered a planet anymore. A solar system is the Sun and the group of planets and bodies that orbit around it.

3. The Sun It’s a medium star. It’s a hot firey ball of gas that makes its own light and heat. The Sun is 27,000,000 degrees. More than 100 earths can fit across it.

4. Inner Planets There are 4 Inner Planets in our Solar System. They are small, rocky, and have craters. They are small and balled shaped.

5. Mercury Mercury is the nearest to the sun. It is the smallest planet. On Mercury a day is as long as are year. It has no atmosphere so there are lots of craters. In the day it’s 750 degrees and at night it’s – 300. The Roman people named Mercury after their Roman fleet messnger. Mercury has no moons.

6. Venus Venus is the hottest planet. It is 900 degrees. The Romans named Venus after their god of love. Venus has a thick carbon dioxide atmosphere. Venus is covered by a layer of sulfuric acid clouds. Volocanos on Venus never run out of lava. Venus has no moons.

7. Earth Earth is the only known planet to support life. It has liquid water and oxygen for people to survive. Earth has 1 moon. It’s protected by a blanket of air called the atmosphere. Earth is called the blue planet because it has so many oceans.

8. Mars Mars was named after the god of war by the Romans. Mars has 2 moons. It is covered in red rocks made of iron oxide. It also has polar ice caps and possibly underground water. It has a thin atmosphere. Mars might have had an ocean in the past.

9. Asteroid Belt The Asteroid Belt is made up of billions of fragments of rock. It is leftover rocks from the creation of the planets. Some pieces dislodged and entered atmosphere where they burn up and are called shooting stars or meteorites.

10. Outer Planets The Outer Planets are made of gases.The 4 planets farthest from the sun are called the outer planets. The 4 outer planets have rings. These outer planets are Jupiter, Saturn, Uranus, and Neptune. The outer planets are the coldest.

11. Jupiter Jupiter is named after their king of all Roman gods. It is the biggest planet in the Solar System. Earth can fit inside it 1,300 times. It has a rocky core that Earth can fit in twice. Jupiter has a red spot that has stayed in the same place for 300 years. It has 63 moons.

12. Saturn Saturn’s rings are the brightest. They are made up of rock, ice, and dust. It has 61 moons. If you put Saturn in a lake it would float.

13. Uranus Uranus is 31,570 miles around. Uranus is 1,781,000,000 from the Sun. Uranus takes 17 hours and 18 minutes to spin once. It takes 84 years to go around the sun once.Uranus is different from the other outer planets because it spins on it’s side. It has 27 moons. Uranus is named after the Greek god of heaven and the ruler of the world.

14. Neptune Neptune is 30,200 miles around. Neptune is 2,788,000,000 miles from the sun. To go around once it would take 17 hours and 50 minutes. To go around the sun it takes 165 years. The Roman people named Neptune after there god of sea. Neptune has white clouds and lots of storms. It has 4 rings. Methain gas makes it blue. Neptune’s biggest moon is Triton. Neptune has a Great Dark Spot that is a strom.

15. Pluto Pluto is not considered a planet for many reasons. Pluto is a dwarf planet. One of the resons are it has a differnt orbit. Sometimes it is closer to the sun than Neptune. Another one is there are 4 rocky planets and 4 gas giants and then there is pluto. Pluto has 3 moons. The Romans named Pluto after their god of death. It would take 30 years to get there. It is smaller than Earth’s moon.

16. You have learned all about Our Solar System, but there are still more mysteries to be discoverd. Space is interesting because space is a big mystery.
