Identify and describe the 3 main categories of trans-Neptunian objects.
The three main categories of trans-Neptunian objects are Planetoids, the Kuiper Belt, and the Oort cloud. Planetoids are dwarf or minor planets, natural satellites, and minor bodies. Planetoids are asteroids. The kuiper belt is a region with icy and rocky objects just beyond the orbit of Neptune which are called Planetoids. Another term for this is Asteroids. The Oort cloud is a huge spherical cloud of comets and dust that extends three light years from the Sun in all directions.
Please add any other info, and tell me if this is correct, thanks :-)
