Our Solar System

1. Jeremy Nack Our Solar System

2. Our Solar System • Part of the Milky-Way Galaxy • Our Solar System: • Sun • Four Inner Planets (Terrestrial Planets) • Mercury • Venus • Earth • Mars

3. Our Solar System • Asteroid Belt • Five Outer Planets (Gas Giants) • Jupiter • Saturn • Uranus • Neptune • Pluto

4. Terms to Know • K – Kelvin, it measures absolute temperature • F – Fahrenheit, Our Measure of Temperature • AU – Astronomical Units, Measure of distance in space (For us the measure of distance from the Sun) • Mph – Miles Per an Hour, measurement of Speed (how fast something is going)

5. Sun • All nine planets orbit the Sun • The Sun’s Surface is called the photosphere • The Sun’s Temperature is 5800K • Which is nearly 10,000 Degrees Fahrenheit

6. Mercury • Closest to the Sun • 8th largest planet of 9 • Small rocky planet like Earth’s Moon • It is Covered by craters • .4 AU’s from the Sun

7. Venus • Full of hot temperatures • Full of carbon dioxide = which creates a blanket of Clouds • Heat gets trapped underneath the thick layer of clouds keeping Venus really Hot! • Surface is like Earth but without water which probably boiled away due to how Hot Venus is • Full of Gentle plains • No hills or Mountains • Second planet from the Sun • 6th Largest of all 9 planets • .7 AU’s

8. Earth • Our Planet • 3rd from the Sun • 5th largest planet of 9 • Earths Surface is very young it was first formed from Erosion and tectonic processes. • 71% of Earth is covered by Water • 21% of Earth’s atmosphere is oxygen, which WE breath! • Earth is the most beautiful planet from space! • 1 AU

9. Mars • 4th planet from the Sun • 7th largest of 9 • Mars is the Second most interesting and beautiful planet (behind Earth) • Lakes and ocean might have once existed on Mars but not any more. • Only other Planet with evidence of Life once existing. • 1.5 AU’s

10. Asteroid Belt • Region between inner planets and outer planets • More than 7000 asteroids have been discovered here • Largest Asteroid by far is called Ceres • Ceres is considered 25% bigger than any other Asteroid • Recently been Considered a Dwarf Planet, Which is a Planet not big enough but close enough to be called a Planet! • 2.77 AU’s

11. Jupiter • 5th planet from the Sun • Largest planet in our Solar System (of 9) • 318 times larger than Earth! • Planet does not have a solid surface due to is gaseous composition • Jupiter has winds that can be as fast as 400 mph • Jupiter also has bands/ rings that go around the planet (they are not as noticeable as Saturn's). • 5.2 AU’s

12. Saturn • 6th Planet from the Sun • 2nd Largest out of 9 • Like Jupiter, Saturn has bands that run around the Planet (Saturn's are much larger and Noticeable than Jupiter). • Saturn is composted of mostly Gas just like Jupiter • 9.5 AU’s

13. Uranus • 7th Planet from the Sun • 3rd Larges of the 9 plants • Like the other gas planets Uranus has bands of clouds that blow around very rapidly • Uranus blue color is due to a gas called methane • 19.6 AU’s

14. Neptune • 8th Planet from the Sun • 4th Largest in Size (out of 9) • Blue color result from a Gas called Methane Just like Uranus. • Has rapid winds and storms • Winds are fastest in Solar System and can reach 2000 km an hour • 30 AU’s

15. Pluto • Farthest Planet from the Sun • Smallest Planet out of the 9 • It is now officially considered a Dwarf Planet! • There is not much known about Pluto surface, etc. • 39 AU’s

16. Conclusion • Scientist’s are Working day and night to always expand their knowledge of our Solar System and with each passing year New Planets are Discovered • Here are some New ones: • Up Coming Assignments: • Project (model of Solar • System) • Test on Planets! • Know the Facts from these Slides 
