... Where do comets come from? Most comets are found in one of two distant regions of the solar system: The Kuiper Belt and the Oort cloud. The Kuiper Belt is a doughnut shaped region that extends from Neptune’s orbit to about 100 times Earth’s distance from the sun. The Oort cloud is a spherical regio ...
