The Kuiper belt is a disc of objects made of ice and rock that orbit our sun just past the orbit of Neptune. There are many objects in the belt believed to be short-period comets. However, there are at least three dwarf planets with more likely to be discovered....

It extends from the orbit of Jupiter at 5.2 AU to the Kuiper belt at 50 AU. Many researchers believe there are undiscovered planets in the solar system, particularly in its outer reaches. In recent years, there has been growing interest in the possibility of a ” Planet X” or “Nibiru”...

Tenth Planet - The Kuiper Belt
Why aren't the Kuiper belt objects planet-size?Dwarf Planets:The region of the Kuiper belt has been found to contain at least 3 dwarf planets, with other discoveries possible. None of these objects, Pluto included, more than a fraction of the size of the Moon, but as they are roughly ...
Like the other dwarf planets, Makemake is located in the Kuiper belt. Diameter: 1,430 km (888 mil) Distance from Sun: 45.8 AU Day: 22.5 hours Orbit: 305 Earth years Natural Satellites: 1 provisional moon Eris Eris is the ninth-largest known object orbiting the Sun, the furthest from the...
The Kuiper Belt is close by. Ceres, the largest asteroid known so far, 7 is close to Pluto. The IAU calls it as a dwarf planet(矮行星). No matter what it is called, Pluto is still out there. No spacecraft has 8 landed on Pluto, but we do know some things about it. It was ...
(as our Moon does). But a dwarf planet does not clear the neighborhood around its orbit and may cross the paths of other objects orbiting the sun. Other dwarf planets include Ceres, whose orbit is in the asteroid belt between Mars and Jupiter, and Eris, an object in the Kuiper belt ...
