KUIPER Belt

Introduction
Space anomalies tend to recur often even within our own Solar System. Lets says things such as planets, moons and even Asteroids belts. Ah yes, there is a second Asteroid belt in our Solar System, well not exactly but similar. Unlike The Asteroid Belt however, this similar belt in space lies a few Astronomical Units farther than it does. This belt is known as The Kuiper Belt. The Kuiper Belt is a belt consisting of small rocks that is left over debris from The early Solar System. The Kuiper belt is much larger than The Asteroid Belt, in measurements it is about 20 times widers and  200 times more massive. The Rookie Asteroid Belt vs The Juggernaut Kuiper Belt to put it simply. 
Farther Out but closer in
The Kuiper Belt lies between the location of The Asteroid Belt and The Oort Cloud. It is further out than the Asteroid Belt and Closer in than The Oort Cloud. These three are very similar in what they consist of by the three's sizes are at much different scales. The Asteroid belt is smaller than the Kuiper Belt while The Oort Cloud is much more colossal taking up space 99 times the size of The Solar System within its boundaries. One is a lot smaller and the other is bigger at a greater scale than that of the former. 
Location
The Kuiper Belt is located past the planet Neptune about 50 Astronomical Units away from The Sun. Some of Neptune's Moons like Triton and and some of Saturn Moon's like Phoebe are believed to have come from The Kuiper Belt. Pluto is within the borders of The Kuiper Belt. The Kuiper Belt consist of failed planets, planetesimals , Asteroids, Meteoroids and fragments of the original pre planetary dust from The Sun. 
​Conclusion
Many dwarf Planets like Pluto are believed to be within The Kuiper Belt. It goes the show that we sometimes need to look deeper into something to find an answer. There may be thousands of Dwarf Planets or maybe even Planets inside of The Kuiper Belt. We may never know that for sure unless we keep observing it. Seek the answer and thou shalt find it.
