4. Our Solar System Our solar system is made up of: Sun
Eight planets (+moons)
Asteroids, Comets, Plutoids

5. Inner Planets
The inner four rocky planets at the center of the solar system are:
Mercury
Venus
Earth
Mars

6. Mercury Planet nearest the sun Covered with craters
Has no moons or rings
About size of Earth’s moon

7. Venus Sister planet to Earth Has no moons or rings
Hot, thick atmosphere

8. Earth Third planet from sun
Only planet known to have life and liquid water
Atmosphere composed of composed of Nitrogen (78%), Oxygen (21%), and other gases (1%).

9. Mars Fourth planet from sun
Appears as bright reddish color in the night sky
Surface features volcanoes and huge dust storms

10. Outer Planets The outer planets composed of gas are : Jupiter Saturn
Uranus
Neptune

11. Jupiter Largest planet in solar system Brightest planet in sky
Giant red spot

12. Saturn 6th planet from sun Beautiful set of rings Largest moon, Titan,
Voyager explored Saturn and its rings.

13. Uranus 7th planet from sun Covered with clouds
Uranus sits on its side with the north and south poles sticking out the sides.

14. Neptune 8th planet from sun Triton largest moon
Great Dark Spot thought to be a hole, similar to the hole in the ozone layer on Earth

15. Outermost Planet? Pluto Mostly ice Smaller than Moon.
Never visited by spacecraft
Orbits very slowly
Moon, Charon, is very close to Pluto and about the same size
2006-”plutoid”

16. Asteroids Between Mars and Jupiter 100,000 rocky bodies
Left over from the beginning of the solar system?
Largest asteroids have been given names

17. Comets Eccentric orbit around sun Central mass covered in ice
Trails icy dust

18. Hailey’s Comet

19. Asteroid belt

20. Kuiper belt
Trillions of objects
30-50 AU from sun
Icy objects
Pluto is a part

21. Kuiper belt

22. Oort cloud Small icy bodies Travel past the Sun
50-100,000 AU from the sun?
2 trillion comets
Small icy bodies
Travel past the Sun
Give off gas and dust as they pass by

23. Oort Cloud

24. Milky way 120,00 light years across 12,000 light year bulge in middle
billion stars
90% dark matter

25. Milky Way
Interactive:

26. Mason MS is in the Virgo Supercluster
Our universe
Mason MS is in the Virgo Supercluster

27. Gravity-Holding it all together

28. What happens if the mass of the center object increases or decreases?
What if the distance of the orbiting object increases or decreases?

29. Phases of the moon

30. Phases of the moon

31. Lunar and solar eclipse

32. Making planets: Q.#4 Must have diagrams complete
Use the balloon as a scale model for the sun (30 cm)
Calculate the scaled size of all the planets and record.
Use play-dough to make the planets to scale
Answer: How many cm from Earth to sun?

33. Doing the math
30 cm = 1,390,000 km
1cm = __________km

34. Tomorrow
Phases of the moon

35. Exit
Write the LT in your own words.
