1. The Inner and Outer Planets

3. The Inner Planets Terrestrial High temperatures Closer to the Sun
Closer to each other

4. Mercury Closest to the Sun Only 88 days to orbit Many craters
Temperature extremes
400C during day, -180 at night
Basically no atmosphere

5. Mercury
Mercury is not the hottest planet even though it is the closest to the Sun

6. Venus Earth’s sister planet Morning and evening star
Thick atmosphere of CO2 and Sulfur
Longer day than year
Spins opposite than other planets
Over 500C all the time
Hottest planet in solar system

7. Venus
The atmosphere of Venus contains a high percentage of carbon dioxide that holds heat in the planet's atmosphere.
The atmosphere of Venus is made of thick clouds of sulfuric acid and carbon dioxide, which makes it very hot.

8. Earth Home sweet home Only planet with sustained life
Hydrosphere (water)
Atmosphere made up of N, O, CO2
Comfy temps

9. Earth
Earth has fewer craters than other terrestrial planets because of its atmosphere (upper) which destroys meteorites.

10. Mars Frozen polar CO2 caps Smaller than Earth
Slightly longer day and year
Very cold
Largest mountain in solar system
Olympus Mons
Thin atmosphere

11. Mars has frozen polar ice caps and is known as the most like Earth.

12. Asteroid Belt Separates the inner and outer planets
Possibly an annihilated planet
Most asteroids hang out here

13. Outer Planets Gas giants No solid surface, just thick atmosphere
All very large
Very far apart from each other
All have rings

14. Jupiter Could hold 1300 Earths Almost big enough to be a star
12 EY = 1 Jovian year
1 Jovian day = 12 EH
Huge storms
Great red spot “hurricane” larger than Earth
Some moons may have water

15. Jupiter is largest planet in the solar system.
Jupiter can fit all of the other planets inside this gas giant and there would still be space left over.

16. Saturn 29 years to orbit Large rings made of ice and dust 10 hour day
Possibly still forming
Tilts itself

17. Saturn
Saturn is known for its’ rings and is the least dense planet. It would float in a swimming pool if we had one big enough to put this planet into.

18. Uranus Blue in color due to methane gas 84 years to orbit
Rotates sideways
Very cold
-250C

19. Uranus
Uranus also has rings, but lies on its side so the rings go around it vertically.

20. Neptune Methane atomosphere 164 years to orbit -250c temps
30 times farther from the sun than Earth

21. Neptune
Neptune is blue because it is mostly made of a gas called methane

22. Pluto
Pluto is a draft planet, because of its size and irregular orbit.
