WASP-7b
WASP-7b is an extrasolar planet discovered in 2008. This 5-day period planet is slightly smaller than Jupiter, roughly the same mass and more dense.
The study in 2012, utilizing a Rossiter–McLaughlin effect, have determined the planetary orbit is strongly misaligned with the equatorial plane of the star, misalignment equal to 86°, making planetary orbit nearly polar.
