1. Our Solar System

2. Solar System A star and all of the objects that orbit around it.
Our solar system is made up of eight planets.

3. Planet
A large object made up of gas or rock that orbits the sun with its own orbit.
With its own orbit is why PLUTO is no longer a planet.

4. Moon
A natural object that orbits a planet.

5. asteroid A rock that revolves around the sun.
We have an asteroid belt between Mars and Jupiter

7. Revolution
How long a planet takes to complete one trip around the sun.
Earth is 365 Days or 1 Earth Year (EY)

8. Rotation The time it takes a planet to go once around its axis.
Earth is 24 hours or 1 earth day. (ED)

9. The Inner and Outer Planets

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

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

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

13. Mercury Radius (Size): 2,440 Km Temperature: 179deg C
Surface Material: Rock
Rings: None
Rotation: 58 (ED)
Revolution: 87 (ED)
Distance from the Sun: 57 Million Miles
Moons: 0

14. 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

15. 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.

16. Venus Radius (Size): 6,052 Km Temperature: 482 deg C
Surface Material: Rock
Rings: None
Rotation: 243 (ED)
Revolution: 224 (ED)
Distance from the Sun: 67 Million Miles
Moons: 0

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

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

19. Earth Radius (Size): 6,378 Km (About 25,000 miles)
Temperature: 15 deg C
Surface Material: Rock
Rings: None
Rotation: 1 (ED) 24 hours
Revolution: 365 (ED)
Distance from the Sun: 93 Million Miles
Moons: 1

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

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

22. Mars Radius (Size): 3,397 Km Temperature: -63 deg C
Surface Material: Rock
Rings: None
Rotation: hours
Revolution: 686 (ED)
Distance from the Sun: 141 Million Miles
Moons: 2

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

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

25. Jupiter Diameter (Size): 142,796 Km Temperature: -145 deg C
Surface Material: Gas
Rings: Yes
Rotation: 10 (Earth Hours)
Revolution: 12 (Earth Years)
Distance from the Sun: 486 Million Miles
Moons: Yes (over 18 named)

26. 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

27. JUPITER 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.

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

29. 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.

30. Saturn Diameter (Size): 120,660 Km Temperature: -175 deg C
Surface Material: Gas
Rings: Yes
Rotation: 10.2 (Earth Hours)
Revolution: 29.5 (Earth Years)
Distance from the Sun: 886 Million Miles
Moons: Yes 18+

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

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

33. Uranus Diameter (Size): 51,118 Km Temperature: -224 deg C
Surface Material: Gas
Rings: Yes
Rotation: 18 (Earth Hours)
Revolution: 84 (Earth Years)
Distance from the Sun: 2,871 Million Miles
Moons: Yes (15)

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

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

36. Pluto
Pluto is not a planet, because of its size and irregular orbit.
