In fact, the first few hundred exoplanets were found by the "radial velocity" technique, which detects tiny motions of a star as it and its planets orbit one another.
Cricket and football were the young Jehue's first loves but his gym teacher Albert King soon spotted something special in his running technique that convinced him he had a future track star on his hands.
The technique employed to find the new planet uses the gravitational field of a star like a lens - magnifying the light from a distant background star.
