An astronomer thinks the solar system might once have had five large gas planets instead of four. This tenth planet would have been as big as Neptune and stood between Saturn and Uranus, this celestial body has for some reason was thrown into space.

Kuiper Belt

That suggests at least David Nesvorny of the Southwest Research Institute in Boulder, Colorado, in The Astronomical Journal. Evidence for his theory can be found in the Kuiper Belt, a region on the edge of the solar system.

Although most objects are scattered in the Kuiper belt of the solar system, running a cluster of some 25,000 pieces of icy rock in the same orbital plane as the planets around the sun. Until now, no one knew why.

To determine on the basis of computer simulations Nesvorny knew where the pieces of rock came from. He discovered that they were ever influenced by the gravity of Neptune. About four billion years ago suddenly Neptune migrated 7.5 million kilometers outward.

Fifth gas giant

Nesvorny has only one explanation: An object passed, probably the fifth gas giant. It is not known what happened to this planet. Nesvorny believes that the celestial body is tossed into space, that altered the orbit of Neptune.

According to several theories, even at this point still holds a vast unexplored planets lurking in our solar system. This planet is also known as Planet X. You think this is an interesting discovery? Thank about sharing it.
