Second backwards planet found, a day after the first

The planet HAT-P-7b, which is about 1.4 times as wide as Jupiter and 1.8 times as massive, seems to orbit its star in the opposite direction to the star's spin (Illustration: Leiden Observatory) Just a day after the announcement of the first 'retrograde' exoplanet, two teams announce the discovery of another – though they disagree on the tilt of its orbit.
