To those who were blasting me about the factual evidence of Oort Clouds, wikipedia has another viewpoint, if that website is allowed here. I have seen others quote it numerous times. From the website:
"The Oort cloud (pronounced /ˈɔrt/ ort, alternatively the pik-Oort cloud IPA: [ˈpik]) is a hypothesized spherical cloud of comets which may lie roughly 50,000 AU, or nearly a light-year, from the Sun." This fits with what Coragyps was stating for the extreme distances of the Oort Cloud.
Note the word "hypothesized".
Also, "Although no confirmed direct observations of the Oort cloud have been made, astronomers believe that it is the source of all long-period and Halley-type comets entering the inner Solar System and many of the Centaurs and Jupiter-family comets as well."
Reading the page in it's entirety I don't see any factual evidence that this cloud exists.
