Above Neptune's trajectories on the conveyor belt outside our Solar System, the formation of a solar system orbit leaves little space objects called "trans-Neptune objects or TNO" that orbit the sun almost in a circular path. But far from the edge of the Solar System, and believed that Neptune, including other giant planet bands, is affecting the gravity of these space objects.
But in 2003, astronomers discovered some disruption in the location of the object outside of Neptune, ie 30 mysterious objects that were more important than other Neptune objects. And could not find an explanation But some astronomers have accepted this unusual trajectory of these objects
It can be influenced by nine planets (nine on the planet), but on the other hand, scientists cannot clearly determine whether there are nine planets. Since nine planets are just six years ago, hypotheses were created to explain an unusual object outside of Neptune.
The story makes scientists from Cambridge University in England. And Beirut American University in Lebanon Create a model of the solar system and the dust plate, consisting of a small ice object with mass up to 10 times the Earth to study gravity. To see how it affects the solar system It is possible that this object of Neptune objects could not be influenced by nine planets.
