  1. Introduction to the Solar System BY: BRIANNA SHIELDS

  2. Do Now • Do other solar systems exist???

  3. GOAL • To be able to describe the bodies found in our solar system and the way in which they move

  4. Become a planet expert……… • 1. Numbered position from sun • 2. Inner or outer planet? • 3. Describe surface? What is it made of? • 4. Number of moons? Rings? • 5. Temperature • 6. Any other interesting info

  5. The planets • Mercury • Venus • Earth • Mars • Jupiter • Saturn • Uranus • Neptune • Pluto

  6. Planetary Distances • Distances between planes measured in Astronomical Units (AU) • 1 AU= distance from Earth to the Sun (150 million km)

  7. Planetary Orbits • Planets revolve around the sun in elliptical orbits (oval) • http://www.amastro.org/at/pl/plo.html

  8. Formation of the Solar System • The solar system formed from a huge swirling cloud of gases and dust specks. The mass fell to the center and became a star (SUN) • Some of the dust and frozen gases stuck together in clumps (large clumps became planets)

  9. MERCURY- The god of commerce and thievery • Closest to sun • Hot days, cold nights • Rocky surface • Revolves quick • No rings or moons • Slow rotation • Iron/metal core

  10. VENUS- God of Love and Beauty • 2nd from sun • Slow rotation- backwards • Solid rock • Clouds- greenhouse effect • No rings or moons • Metal core

  11. EARTH • 3rd from sun • Moderate temps • Metal core, rocky surface • One moon, no rings • Life, liquid water

  12. MARS- God of War • 4th from sun • Rust color w/ pink sky • Icecaps • Metal core, rocky surface • No rings, 2 moons

  13. JUPITER- King of Gods • 5th from sun • Largest • Gas surface, rock core • Colored clouds, storms • Thin ring, 12 moons • Great red spot • Shortest day - 10 hrs

  14. SATURN- Father of Jupiter • 6th from Sun • Least dense, made of gas • Large, spins quick • High winds • 7 rings, 18 moons

  15. URANUS- God of the Heavens • 7th from Sun • Large, gaseous • Blue, thick clouds • Rock & ice • 15 moons, 11 rings • Spins sideways

  16. NEPTUNE- God of the Sea • 8th from sun • Large, gaseous • Windiest, scooter cloud • Great dark spot • 8 moons, 4 rings • Rock core

  17. PLUTO- God of the Underworld • 9th from Sun • Cold, ice and rock surface • Eccentric orbit • Double planet • Moon-Charon

  18. INNER PLANETS Hard, rocky surface Atmosphere Metal core Warm temps No/few moons No rings Mercury, Venus, Earth, Mars OUTER PLANETS Gaseous surface Giant size Colorful clouds Many moons Many rings Cold/icy temps Exception: Pluto Jupiter, Saturn, Uranus, Neptune Inner vs. Outer Planets

  19. Solar System Websites • What are the actual positions of each planet in their orbit right now? • Shape of each planet’s orbit • Comparing planet size

  20. Assessment • What is the difference between a meteoroid, meteorite and a meteor? • What is the difference between an asteroid and a meteoroid? • How does a comet differ from an asteroid and meteoroid? • What is the energy source for our solar system?

  21. Assessment • Which planet is the largest? • Which planet is fourth from the sun? • Which planet is known as the double planet and why? • Name the four inner planets • What is one characteristic of all/most outer planets • What is one characteristic of all/most inner planets
