Strange 'inside-out' planetary system baffles astronomersThis artist's impressions shows the unusual set up of the solar system around the LHS 1903 star. In our Solar System, the four planets closest to the Sun are small and rocky, while the four farther out are gas giants. Scientists had thought this planetary order -- rocky first, then gaseous -- was consistent across the universe. Puzzled by the weird LHS 1903 planetary system, the team of astronomers tried to figure out what could have happened. "Historically, our planet formation theories are based on what we see and know about our Solar System," said Isabel Rebollido, a planetary disc researcher at the European Space Agency.
