The Oort Cloud is a theorized spherical cloud of predominantly icy planetesimals believed to surround the Sun to as far as halfway to the nearest star. It is thought to be the source of long-period comets. The Kuiper Belt is a disc-shaped region beyond Neptune's orbit populated by numerous icy bodies and extending from 30 to 50 AU from the Sun, including short-period comets and objects like Pluto. New Horizons is an unmanned spacecraft on a mission to conduct the first flyby and study of Pluto and to fly by and study one or more other Kuiper Belt objects after performing a flyby of Jupiter in 2007.

1. OORT CLOUD OverviewTheorized by Jan OortExtends from 5,000-100,000 AU’sHome to long-period cometsNever been observed, only a theoryContains 0.1-2 trillion cometsEdge of our solar system

3. Long-Period CometsTake over 200 years to orbitFly into the inner solar systemCaused by gravitational perturbationHale-Bopp, Orbit:4200 years

4. Kuiper Belt OVERVIEWDiscovered by Gerard KuiperJust beyond NeptuneExtends from 30-50 AU’sHome to short-period cometsObjects in the Kuiper Belt: KBO’s+1,300 comets identifiedMostly on the ecliptic plane

5. Short-Period CometsOrbit of less than 200 yearsCome from the Kuiper BeltOrbit the SunHale-Bopp, Orbit:4200 years

6. KBO’sPlutoSednaHaumeaTriton (It’s complicated)

7. PlutoAverage temperature: -230 calciusSurface: nitrogen, methane, carbon dioxide icesMoons: Charon, Nix, HydraIs a key object in the New Horizons MissionOrbit: 248 yearsCharon couldn’t be seen until 1978

8. SednaFarthest object discovered in the Kuiper BeltOrbit: 12,000 yearsSlightly smaller than Pluto130 light hours from the Sun

9. HaumeaVery interesting objectListen to Suman’s whole speal

10. TritonNeptune’s moonGeologically active with water and ammoniaWas once a KBOOn a decaying orbit with NeptuneWill most likely form rings like Uranus
