The Kuiper Belt is a region in our solar system beyond the planet Neptune, consisting of small bodies and dwarf planets. Pluto is one of the larger objects, and surprisingly until the nineties the only one to be discovered. In this research we looked at the distribution of the Kuiper Belt Objects (KBO's) and their behaviour. With the data available at that time, we noticed that there was a portion in resonance with Neptune, Pluto among them. These trans-Neptunian objects could orbit the sun unharmed by the influence of Neptune. Also we saw a giant gap in the observations, but when we took the data to a 3D-simulation in the CAVE - an immersive virtual reality environment from SARA - we saw that with the ages this gap would disappear: it's just an effect of selective observations.
