Solar system & planets

  1. 1. The Universe, Solar System, and Planets I
  2. 2. Edwin Hubble at Mt. Wilson Hubble guiding the Hooker 100 inch telescope in 1923. The Hooker 100 inch telescope atop Mt. Wilson near Pasadena, CA. It was the largest telescope in the world from 1917-1947.
  3. 3. Deep Hubble Space Telescope Image A deep image of an “empty” portion of the sky with the Hubble Space Telescope reveals that the universe is filled with galaxies- many just like our own. The light we see from the most distant galaxies has traveled approximately 10 billion years to reach us.
  4. 4. The Solar System - Its Origin and Early Development Our solar system, part of the Milky Way galaxy, consists of the Sun, nine planets, 64 known moons, many asteroids, millions of comets and meteorites, as well as interplanetary dust and gases
  5. 5. Vocabulary • To magnify: To make an object appear larger

  10. 10. • Moon: A small rounded body in orbit around a planet.
  11. 11. • Solar system: It is made up of the sun, planets, moons and other objects that orbit the sun.
  12. 12. • Space probe: A craft that helps scientists explore outer space.
  13. 13. A galaxy: A collection of stars, gas and dust bound together by gravity
  14. 14. • A comet: A small frozen mass of gas and dust revolving around the sun
  15. 15. Asteroids-Meteorites Visitors from Outer Space • Asteroids are rocks that revolve around the sun, when the rock breaks the layers of planet Earth they become shooting stars. • Meteorites are believed to be pieces of material that originated in the formation of the Solar System about 4.6 billion years ago – Stones - composed of iron and magnesium silicates, about 93% of all meteorites – Irons - composed of iron and nickel alloys – Stony-Irons - nearly equal amounts of iron and nickel and silicate minerals
  16. 16. Movements of planet Earth • Rotation: The Earth spins around its own axis • Revolution: The Earth revolves around the sun.
