Exoplanets discovered by WASP together with ESO telescopes that unexpectedly have been found to have retrograde orbits are shown here. In all cases, the star is shown to scale, with its rotation axis pointing up and with realistic colors. The exoplanets are shown during the transit of their parent star, just before mid-transit. The last object at the lower right is for comparison and has a "normal" orbital direction. The size of each image is 3 solar diameters.
