WASP-7 b

This 5-day period planet, orbiting a round the star WASP-7, is slightly smaller than Jupiter, roughly the same mass and more dense.

[2] 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±8°, making the planetary orbit nearly polar.

[3] The orbit is also slightly eccentric, which is surprising given the tidal circularization timescale of below 650 million years.

[1] The measured temperature on the planetary dayside is 1393+80−82 K.[1] Sodium was detected in the planetary atmosphere in 2022.
