Outlandish planet has wonky orbit

SYDNEY: Astronomers have found an extrasolar planet with an "outlandish orbit" that circles its star either backwards, or at an angle of around 90º to the orientation of the star's rotation.

Planets in our own Solar System orbit in the same plane and direction as the Sun's own rotation. This led astronomers to propose the 'nebula hypothesis' - whereby planets form from a flat, swirling disk of gas around a proto-Sun.
