  • 1. Our Solar System

  • 2.
  • 3. Our Solar System
    Our Solar System consists of:
    -the Sun
    -8 planets and their moons
    -dwarf planets
    -asteroids
    -Kuiperbelt objects
    -Oort Cloud
    -comets
    -meteoroids
    -interplanetary dust
  • 4. The Sun
    The largest object in the solar system
    Contains 99.8% if the Solar System’s total mass
    4.6 billion years old
    It’s strong gravitational pull holds all the planets in orbit
  • 5. The Planets
    8 total
    Mars, Venus, Earth, Mercury, Jupiter, Saturn, Uranus, Neptune
    Two categories
    Terrestrial Planets
    Jovian Planets
  • 6. The Terrestrial Planets
    “Earth-like”
    Mars, Venus, Earth, and Mercury
  • 7. The Jovian Planets
    “Jupiter-like”
    Jupiter, Saturn, Uranus, and Neptune
  • 8. Moons
    Terrestrial Planets
    Mercury- 0 moons
    Venus- 0 moons
    Earth- 1 moon
    Mars- 2 moons
    Jovian Planets
    Jupiter- 63 moons
    Saturn- 61 moons
    Uranus- 27 moons
    Neptune- 13 moons
  • 9. Asteroids
    Rocky, metallic objects that orbit the Sun
    Too small to be considered planets
    Can range in size from 1,000 km to the size of pebbles
    Most asteroids are found in the Asteroid Belt
    Between Mercury and Jupiter
  • 10. Comets
    Made of frozen gas and frozen water
    Invisible except when near the Sun
    Their orbits take them far outside the orbit of Pluto
    Most are located in the Oort Cloud
  • 11. Meteoroids
    Little chunks of rock and debris in space
    Become meteors (shooting stars) when the fall through a planet’s atmosphere.
    Chunks that hit the ground are called meteorites
  • 12. Interplanetary Dust
    Formed in the chemical reactions of interstellar molecular clouds
    Nitrogen and deuterium enrichments
