Drawings showing the orientation of the observer relative to the planet at its periastron passage for each of the five exoplanets (not to scale). The parent star is represented by a red star symbol and the planet by a disk, with the dayside coloured yellow and the nightside black. The blue arrow indicates the direction towards Earth. A solid black line shows the scale of the orbit. The orbital trajectory along which the planet moves in an anticlockwise direction is shown as a dashed grey line. The planet rotates anticlockwise as well.
