    The oort cloud and the kuiper belt2 The oort cloud and the kuiper belt2 Presentation Transcript

    • OORT CLOUD Overview
      Theorized by Jan Oort
      Extends from 5,000-100,000 AU’s
      Home to long-period comets
      Never been observed, only a theory
      Contains 0.1-2 trillion comets
      Edge of our solar system
    • The Oort Cloud
    • Long-Period Comets
      Take over 200 years to orbit
      Fly into the inner solar system
      Caused by gravitational perturbation
      Hale-Bopp, Orbit:4200 years
    • Kuiper Belt OVERVIEW
      Discovered by Gerard Kuiper
      Just beyond Neptune
      Extends from 30-50 AU’s
      Home to short-period comets
      Objects in the Kuiper Belt: KBO’s
      +1,300 comets identified
      Mostly on the ecliptic plane
    • Short-Period Comets
      Orbit of less than 200 years
      Come from the Kuiper Belt
      Orbit the Sun
      Hale-Bopp, Orbit:4200 years
    • KBO’s
      Triton (It’s complicated)
    • Pluto
      Average temperature: -230 calcius
      Surface: nitrogen, methane, carbon dioxide ices
      Moons: Charon, Nix, Hydra
      Is a key object in the New Horizons Mission
      Orbit: 248 years
      Charon couldn’t be seen until 1978
    • Sedna
      Farthest object discovered in the Kuiper Belt
      Orbit: 12,000 years
      Slightly smaller than Pluto
      130 light hours from the Sun
    • Haumea
      Very interesting object
      Listen to Suman’s whole speal
    • Triton
      Neptune’s moon
      Geologically active with water and ammonia
      Was once a KBO
      On a decaying orbit with Neptune
      Will most likely form rings like Uranus
    • New Horizons
      Launched in Cape Canaveral Air Force Station, Florida
      Traveling to the Kuiper Belt
      Tested Equipment at Jupiter
      Only the fifth spacecraft to travel inter-planet space
