Lesson 7 solar system

  1. 1. Lesson 7THE SOLAR SYSTEM
  2. 2. Formation of the Universe
  3. 3. 7.1 Solar System Formation What do you think about this picture? Who can explain this picture?
  4. 4.  4
  5. 5. 
  6. 6. Planetary Composition, Distancefrom the Sun, and Melting Point
  7. 7. 7.2 Members of Solar System divide by formation and the elements in 4 region 1. Inner planets 2. Asteroid belt 3. Outer planets 4. Oort’s cloud
  8. 8. 1. Inner planets The terrestrial planets Between the Sun and Asteroid belt Mercury, Venus, Earth ,Mars The planets that are small and rocky, Metal Core.
  9. 9. 2. asteroid belt Most asteroids lie between the orbits of Mars and Jupiter. An asteroid is a small, rocky body whose diameter can range from a few hundred kilometers to less than a kilometer. Example : Gaspra, Ceres, Pallas
  10. 10. 3. Outer planets Giantplanets, The Jovian planets) The Giant planets, with huge gas , Hydrogen and Helium. Jupiter, Saturn, Uranus, and Neptune.
  11. 11. 4. Oort’s cloud The Oort’s cloud are comets with long orbital periods appear to be distributed in all directions from the sun, forming a spherical shell around the solar system
  12. 12. Meteoroid A meteoroid is a small, solid particle that travels through space. A meteor is the luminous phenomenon observed when a meteoroid enters Earth’s atmosphere and burns up, popularly called a shooting star A meteorite( ) is any
  13. 13. Comet’s Tail Points Away from the Sun
  14. 14. Kuiper belt object Like the asteroids in the inner solar system Most Kuiper belt comets move in nearly circular orbits that lie roughly in the same plane as the planets Example Objects : Pluto , Eris
  15. 15. 7.3 The Sun The Sun is informally designated as a yellow dwarf, based on spectral class, is G2 surface temperature of approximately 5778 K (5505 C) It has a diameter of about 1,392,684 km about 109 times that of Earth 30
  16. 16.  The Sun device into 2 part 1. the Solar Interior. 2. Atmospheric Layers.
  17. 17. The Solar Interior :divide into 3 layer 1. Core : A temperature of Core close to 15.7 million kelvin. Energy is produced by nuclear fusion. 2. Radiation zone 3. Convection zone
  18. 18. Atmospheric layers : divideinto 3 layer 1. photosphere 5,800 2. chromosphere 25,000 3. corona
  19. 19.  Solar wind 200- 900 solar flare solar storms
