Other planetiods

  • Objects in Kuiper Belt
    –  region of the solar system beyond the orbit of Neptune, believed to contain many comets, asteroids, and other small bodies made largely of ice.
    –  including Pluto and Charon are often termed Trans-Neptunian Objects (TNOs) because they are located beyond the orbit of the planet Neptune.
    –  more than 100,000 Kuiper Belt Objects (KOBs) have been discovered.
    –  70,000+ KBOs that are more than 60 miles in diameter.
  • in the outer reaches of KBOs
    –  more than 80 AU from the Sun; astronomers have recently discovered several objects that rival or greater in size of Pluto.
  • the largest object
    Eris – it has a diameter of about 1,562 miles and also has a single moon – Disnomia.
