A planet expelled from the Solar System


New research suggest that one fifth giant planet, the other four are Uranus, Saturn, Jupiter and Neptune, was disqualified from our system about 4,000 million years. That mysterious world today could be thousands of light years away and, which is just as surprising, it is possible to have moons that, if they meet the appropriate conditions are still warm enough to support life. A summary of the study can be found at arXiv.org.
