The Final Frontier Space
WHAT IS SPACE? HOW BIG IS…..SPACE? HOW DO WE MEASURE SPACE?????
Space is………. (you fill in the blank)
How BIG is space anyway???
“When I think of the size of space I think……………..
“I think we measure the size of space by”….
LET’S PLAY! Near or Far, Big or Small?
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……..
Astronomical Unit AU DRAW THIS CHART IN YOUR JOURNAL
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
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
Solutions Saturn = 9.5 AU’s 9.5 x 93m JUPITER = 5 AU’s 5 x 93m = 465 Jupiter is 465,000,000 miles away!!! Saturn = 9.5 AU’s 9.5 x 93m 9.5 x 93 = 883,500,000 miles away !!!
Let’s get some perspective on this solar system deal… https://www.youtube.com/watch?v=zR3Igc3Rhfg&t=31s
