6. Earth Location and Movement • Third planet from the sun in our solar system • Not too close and not too far away, good conditions for life • Rotates every 24 hours on its axis of 23.5° • Orbits the sun every year (365¼ days) MENU

7. Moon Physical Characteristics • ¼ the size of Earth • Less mass than Earth • Weaker gravitational pull than Earth • Brightest object in the sky after the sun • Does not give off its own light, but reflects the sun’s light

8. Moon Physical characteristics • Surface has dark volcanic flows called Maria (singular Mare). • Has no atmosphere, wind or weather • Diameter: 2,000 miles • Covered in craters and dust

9. Moon Location and Movement • Orbits Earth • Earth’s only natural satellite • Spins once on its axis in the same amount of time it takes to orbit Earth (about one month) • We always only see one side of the moon. • Has eight phases MENU

10. SUN Physical Characteristics • Surface Temp: 9,941°F • Diameter: 110x wider than the Earth • Core Temp: 24.5 Million°F • Creates energy using nuclear fission • Three layers: core, radiative zone, and convection zone • Sunspots: Darker spots on the surface which are cooler Click on the moving picture to find out how long it takes for the sun’s light to reach the earth!

11. SUN Physical Characteristics • A star of hot, glowing gases • Made of mostly hydrogen and helium • Provides heat and light to Earth • Produces solar flares: magnetic storms that erupt 1,000’s of miles outside of the sun

12. SUN Location and Movement • Heliocentric: Sun is the center of solar system • Spins on its axis • Does not make a revolution MENU
