1. 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

2. The Oort Cloud

3. Long-Period Comets Take over 200 years to orbit Fly into the inner solar system Caused by gravitational perturbation Hale-Bopp, Orbit:4200 years

4. 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

5. Short-Period Comets Orbit of less than 200 years Come from the Kuiper Belt Orbit the Sun Hale-Bopp, Orbit:4200 years

6. KBO’s Pluto Sedna Haumea Triton (It’s complicated)

7. 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

8. Sedna Farthest object discovered in the Kuiper Belt Orbit: 12,000 years Slightly smaller than Pluto 130 light hours from the Sun

9. Haumea Very interesting object Listen to Suman’s whole speal

10. 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

11. 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
