  1. The objects in the Oort Cloud and in the Kuiper Belt are presumed to be remnants from the formation of the solar system about 4.6 billion years ago. The Kuiper Belt extends from about 30 to 55 AU and is prob-ably populated with hundreds of thousands of icy bodies larger than 100 kilometers (62 miles) across and an estimated trillion or.

    The Kuiper Belt shouldn't be confused with the Oort Cloud, which is a much more distant region of icy, comet-like bodies that surrounds the solar system, including the Kuiper Belt. Both the Oort Cloud and the Kuiper Belt are thought to be sources of comets.

  4. Dec 14, 2018 · The Kuiper Belt shouldn't be confused with the Oort Cloud, which is an even more distant, spherical region of icy, comet-like bodies that surrounds the solar system, including the Kuiper Belt. But both the Oort Cloud and the Kuiper Belt are thought to be sources of comets.

    The Kuiper belt is distinct from the hypothesized Oort cloud, which is believed to be a thousand times more distant and mostly spherical. The objects within the Kuiper belt, together with the members of the scattered disc and any potential Hills cloud or Oort cloud objects, are collectively referred to as trans-Neptunian objects (TNOs).

  6. Aug 29, 2022 · But what’s beyond the Kuiper belt? Beyond the fringes of the Kuiper belt is the Oort Cloud. Unlike the orbits of the planets and the Kuiper Belt, which are pretty flat like a disk, It's a giant spherical shell surrounding the sun, planets, and Kuiper Belt Objects. Like a big bubble with thick walls around our solar system.
