The Sun, Moon, and Earth

THE SUN, MOON, AND EARTH

HOW FAR AWAY ARE THEY?

CAN THEY SUPPORT LIFE?

THE SUN •Really BIG star

•Burning ball of gases

•Gives life to Earth

• Planets revolve around the sun

SUN FACTS• Temperature: 9,932

degrees F

• Contains Hydrogen and Helium

• 1 Million Earths could fit inside!

DISTANCE• Light takes 8 minutes to

reach Earth• 117 years to Drive • 19 years to fly•Distance from Earth:

93,205,679 Mileshttp://en.wikipedia.org/wiki/Speed_of_light#mediaviewer/File:Earth_to_Sun_-_en.png

CAN THE SUN SUPPORT LIFE?• NO!

• TOO hot

• No water

• No Oxygen

• Only Hydrogen and Helium

• *why haven't we visited?

THE EARTH• Known as the ‘Blue

Planet’

• 70% covered in water

• Temperature: -125 130

• Circular or flat?

ORBIT AND ROTATION

•1 year to “orbit” the sun

•1 day is created by rotation

EARTH FACTS • Temperature: 61 F• Contains oxygen• Earths speed: 67,000

mph •Gravity

-like a magnet-pulls everything to it

CAN EARTH SUPPORT LIFE?• YES! •Only planet with

water• Lots of Oxygen•Only planet that has

life

THE MOON• Creates tides

•Has mountains

• Craters

-created by comets

MOON FACTS• Temperature in day: 225 F

• Temperature at night: -307 F

• Contains Hydrogen and Helium

• 50 moons could fit inside Earth

DISTANCE

•The moon is 250,000 miles away

•1 year to drive

•3-weeks to fly

MOONS GRAVITY•Less gravity than

Earth

•Your weight on the moon: weight/6

•Neil Armstrong

CAN THE MOON SUPPORT LIFE?

•NO!

• Too hot/ too cold

•No Oxygen

•No water

•Why can Astronauts visit?

TOTAL DISTANCES • Sun from Earth: 93,205,679

miles away

•Moon from Earth: 250,000 miles away

BIG DIFFERENCES•Temperature

•Gasses in the air

•Contains water?
