• The Kuiper Belt could contain hundreds of thousands of icy bodies that range in size from small chunks of ice to worldlets larger than 100 kilometres across.
•Astronomers have tracked most short-period comets from their origins in the Kuiper Belt. These are comets with orbital periods of 200 years or less.
• There could be more than a trillion comet nuclei in the main body of the Kuiper Belt.
• The largest Kuiper Belt Objects are Pluto, Quaoar, Makemake, Haumea, Ixion, and Varuna. These are often also referred to as Trans-Neptunian Objects (TNOs).
• New Horizons Flew by Pluto in the Kuiper belt in 2015.
• Astronomers have found structures similar to our Kuiper Belt around at least nine other stars. Hubble Space Telescope imaged discs around the stars HD 138664 in the constellation Lupus, and HD 53143 in the constellation Carina.
• The ices in the Kuiper Belt date back to the formation of the solar system. They contain clues to conditions in the early solar nebula.
