1. OORT CLOUD Overview
Theorized by Jan Oort
Extends from 5,000-100,000 AUs
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 AUs
Home to short-period comets
Objects in the Kuiper Belt: KBOs
+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. KBOs
Pluto
Sedna
Haumea
Triton (Its 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 couldnt 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 Sumans whole speal
10. Triton
Neptunes 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
Travelingto the Kuiper Belt
Tested Equipment at Jupiter
Only the fifth spacecraft to travel inter-planet space
