There are scientists from Lund University who arrived at the somewhat unusual theory to those with a computer simulated model investigated the story behind the plane 9, the controversial hidden ice that probably are farthest out in our solar system.
Right to level 9 is so lonely to the researchers to consider how it actually got there. And now, one has been able to establish that it may have belonged to another solar system from the beginning and thus be an exoplanet, but the sun sometime during the solar system’s youth, when the stars were much closer, took the opportunity to steal the planet to orbit instead.
the likelihood of it this scenario is very small, but may well be true in spite of it. It says Alexis Brandeker, associate professor in the Department of Astronomy at Stockholm University.
– When you exclude all possibilities impossible it is to end the very untrue possibility that must be the right one, he notes.
