1. The Inner and Outer Planets

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

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

4. 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

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

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

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

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

9. 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

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

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

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

13. Pluto
