There could be another giant planet behind Neptune. This was told by astronomers who study the configuration of the solar system, writes the journal Astronomy and Astrophysics.
Experts with the help of computer simulations have found out that there should be another planet in the solar system, but it “disappeared”.
Almost nothing is known about the mysterious planet. Scientists suggest that in its characteristics, it probably closely resembled Mars or Earth. The space object could eventually be simply pushed out of the solar system by gas giants – Jupiter, Saturn, Uranus and Neptune, astronomers say.
