This study challenges traditional models of solar system formation ... and inclinations of the giant planets' orbits have been a longstanding puzzle in planetary science," the authors write.

How did all the planets form, and why did they end up in the orbits that they did? The formation of the solar system is a challenging puzzle for modern astronomy and a terrific tale of extreme ...
