  1. Today Hand in any work needed. Get out a small piece of paper, PUT YOUR NAME ON IT. When bell rings the quiz will start and you will have 1 minute per question to answer.

  2. Question 1 What planet is closest to the sun?

  3. Question 2 What planet isn’t a planet anymore?

  4. Question 3 Which planet has an eccentricity closest to Earths?

  5. Question 4 What are the Jovian Planets in order?

  6. Question 5 What are the Terrestrial planets in order?

  7. Mini Quiz • What planet is closest to the sun? • Mercury • What planet isn’t a planet anymore? • Pluto • Which planet has an eccentricity closest to Earths? • Neptune • What are the Jovian Planets in order? • Jupiter, Saturn, Uranus, Neptune • What are the Terrestrial planets in order? • Mercury, Venus, Earth , Mars

  8. Other space stuff

  9. Vocabulary Big bang theory Asteroids Meteors Comets Fusion Prominence Flare Sunspot

  10. Big Bang Theory Beginning of our universe. Approximately 13 BYA. A supernova blew all the matter from the center of the universe outward. We can measure this with the red shift spectra lines

  11. Asteroids • 1000 km in diameter • Mini planets • Why aren’t they round • Not enough gravity to make them round • What’s up with the holes? • Between Jupiter and Mars.

  12. Meteors Most are a the size of a grain of sand to baseball. Smallest object in space viewed with the eye. Meteor Shower (shooting stars)

  13. Comets • Revolves the Sun on a periodic path. • Called dirty Snowballs • Made of frozen gasses and dirt/debris

  14. Sun’s properties • Sun is a average star in the Main Sequence. • 5800 K @ the surface • 15 million K @ the core • Made of mostly H and He • 700,000 Km (Earth is about 12,000 Km)

  15. Layers • Photosphere • Sunspots • Prominences • Corona – Outer surface • Convection zone + Chromosphere • Radiation Zone • Core

  16. Fusion Nuclear Fusion is when Hydrogen is combined to form Helium. H+H= He + Radiation

  17. Prominences & Flares • Prominences • When hot gasses are ejected from the surface and return in a loop. • Caused by magnetic field • Flares • When hot gasses are ejected and removed from the sun. • Caused by magnetic field.

  18. Sun Spots • What the heck? • Dark spots on the sun • Caused by cooler gasses coming to the surface. • Shows the Suns rotation

  19. Effects of the Flares on Earth Northern Lights Power outages
