1. The Final Frontier
Space

2. WHAT IS SPACE?
HOW BIG IS…..SPACE?
HOW DO WE MEASURE SPACE?????

3. Space is………. (you fill in the blank)

4. How BIG is space anyway???

5. “When I think of the size of space I think……………..

6. “I think we measure the size of space by”….

7. LET’S PLAY! Near or Far, Big or Small?

8. The answer is..we measure space in ASTRONOMICAL UNITS
ONE ASTRONOMICAL UNIT is THE DISTANCE TO THE SUN FROM EARTH
93m MILES
Write out 93M miles……..

9. Astronomical Unit AU
DRAW THIS CHART IN YOUR JOURNAL

10. How to understand AU’s of planets
Multiply the number of AU’s x 93 M miles:
Example: Earth = 1 AU (the distance to the Sun)
1 AU = 93,000,000 miles
93,000,000 x 1 = 93,000,000 miles
Earth is 93,000,000 miles to the Sun

11. Try some more…. How many miles away is Jupiter? Saturn?
Jupiter = 5 AU’s How many miles?
Saturn = 9.5 AU’s How many miles?
Solution:
Take the number of AU’s of the planet, multiply x 93 million to get miles away

12. Solutions Saturn = 9.5 AU’s 9.5 x 93m
JUPITER = 5 AU’s x 93m = 465
Jupiter is 465,000,000 miles away!!!
Saturn = 9.5 AU’s x 93m
9.5 x 93 = 883,500,000 miles away !!!

13. Let’s get some perspective on this solar system deal…
