Quote:(PhysOrg.com) -- A new study published on arXiv.org shows that, based on computer simulations, Jupiter, Saturn, Uranus and Neptune may not have been the only gas giants in our solar system. According to David Nesvorny from Colorado’s Southwest Research Institute, our current solar system could never have happened without the existence of a fifth planet.
Interesting, thanks
