1. The Solar System

2. Our Solar System In order Mercury Venus Earth Mars Asteroid Belt
Jupiter
Saturn
Uranus
Neptune
Kuiper Belt
Oort Cloud

3. Terrestrial Planets Mercury Venus Earth Mars
All have a rocky crust, a denser mantle, and a very dense core

4. The Jovian Planets Jupiter, Saturn, Uranus and Neptune
A solid rock core
A liquid mantle
An outer gas layer
A ring system

5. Mercury: Closest to the Sun
1 solar orbit takes 88 days
Rotates on axis every 58.6 days
Temperatures range from 425 degrees C to -150 degrees C

6. Venus: The 2nd Planet
Atmosphere is made of sulfuric acid clouds and CO2
Surface is covered in faults, lava, and volcanoes
Temperatures in excess of
480 degrees C

7. Mars: 4th from the Sun Has polar ice caps made mainly of CO2
27 degrees C during the day
-125 degrees C at night
Orbits the sun every 637 days

8. Jupiter: The 5th Planet Takes 11.9 years to orbit the sun
Surface is made of alternating light/dark bands of gas

10. Saturn: The 6th Planet 29.7 years to orbit the sun
Known for its rings, which are made of rock and ice

11. Uranus: The 7th Planet
Takes 84 years to orbit the sun
-200 degrees C

12. Neptune: The 8th Planet 165 years to orbit the sun
Gives off 2.7 times more
heat than it receives
Fastest wind in the solar system (2200 km/hr)

13. Asteroid Belt Asteroid: Solid rock masses floating in space
Asteroid Belt: Zone of multiple asteroids between Mars and Jupiter

14. Kuiper Belt
Area of objects from the orbit of Neptune (30.1 AU) to 50 Au from the sun
Smaller objects, hard to see and identify (size & light)

15. The Oort Cloud Outer most area of our solar system
50,000AU to 100,000AU distance from the sun
Spherical cloud of comets

16. Comets A mass of rock, gas, and dust that orbits the sun
Usually has a highly elliptical orbit
Tail is caused by solar wind flying past the body of the comet

17. Meteors, Meteoroids, & Meteorites
Meteoroids are any rock or ice fragment traveling in space
A meteor is the light made when a meteoroid passes through our atmosphere
A meteorite is any piece of a meteoroid that survives its trip through the atmosphere and hits our surface
