  • 2. Things in our Solar System What is an elliptical orbit?
    • The Sun
    • Planets
    • Moons
    • Comets
    • Asteroids and Meteoroids
    • Dwarf Planets
    • Kuiper Belt Objects
  • 3. Our Sun
    • Description: star at the middle of our solar system made of hot plasma
    • Size: 865,400 miles across
    • Composition: Helium & Hydrogen (and a little bit of everything else)
    • Location in space: 30,000 light years from the center of the Milky Way
    Price Tag: $83 trillion
  • 4. Planets
    • Description: celestial bodies moving in elliptical orbit around a star
    • Average size: 3,032 miles – 12,400,000 miles
    • Composition: Rocky (mineral) or gaseous (hydrogen, helium)
    • Location in space: edge of the Milky Way
    • Examples: Mercury, Venus, Earth, Neptune, Jupiter, etc.
    Price Tag: $36-87 billion each
  • 5. Moons
    • Description: a natural satellite (celestial body orbiting a planet)
    • Average size: 310 km - 3,476 km (2,160 miles)
    • Composition: rock (mostly aluminum and silicon oxides)
    • Location in space: orbiting around planets
    • Examples: Io, Europa, Calisto, Luna
    Price Tag: $ 28 billion
  • 6. Comets
    • Description: celestial object made of ice and dust showing a tail when near the sun
    • Average size: Miami, FL or Jupiter
    • Composition: ice, gasses, ammonia, dirt and carbon compounds
    • Location in space: typically originate from the Kuiper Belt or Oort cloud, orbiting around the sun
    • Examples: Haley’s, Hug-bell 1, Johnson-1 , Bus-1, Hale-Bopp
    Price Tag: $3-8 million
  • 7. Asteroids
    • Description: large rocky body orbiting the sun
    • Average size: tens of meters across up to 1000 km wide
    • Composition: metal & rock
    • Location in space: mostly in belt orbiting between Mars & Jupiter
    • Example: Griffin, Daniel, Dick, Andrewmerrill
    Price Tag: $250,000 and up
  • 8. Meteoroids
    • Description: small body moving in the solar system that would become a meteorite if it enters Earth’s atmosphere
    • Average size: sand to boulder-size (up to 300 yards across)
    • Composition: rock and ice
    • Location in space: everywhere, orbiting planets
    • Examples: Murchison, Allende,
    • Peeskill
    Price Tag: $200 - $75,000
  • 9. Dwarf Planets
    • Description: celestial body orbiting the sun, massive enough to be rounded by its own gravity, but has not cleared its neighboring region of planetesmals and is not a satellite
    • Average size: 1,010 km across
    • Composition: traces of methane, hydrogen & helium atoms
    • Location in space: near the orbits of Jupiter and beyond
    • Examples: Pluto, Eris, Ceres, Sedna
    Price Tag: $25 to 30 billion
  • 10. Kuiper Belt Objects
    • Description: large chunks of ice and rock, minor planets from which most comets originate
    • Average size: unknown
    • Composition: frozen volatiles (gases such as methane, ammonium and water)
    • Location in space: ring outside of Neptune’s orbit
    • Examples: Object 1993SC, Quaoar, Binary KBOs
