WASP-7 b
WASP-7 b is an extrasolar planet discovered in 2008. This 5-day period planet, orbiting a round the star WASP-7, is slightly smaller than Jupiter, roughly the same mass and more dense.
A study in 2012, utilizing the Rossiter–McLaughlin effect, determined the planetary orbit is strongly misaligned with the equatorial plane of the star, with misalignment equal to 86°, making the planetary orbit nearly polar. The orbit is also slightly eccentric, which is surprising given the tidal circularization timescale of below 650 million years.
