Everybody was more or less happy with this story until 51 Peg and its weird planet came along. How could a giant planet form so close to a star without being sucked ...

Earth-sized planet found just outside solar system
... The European team detected the planet by picking up the tiny wobbles in the motion of the star Alpha Centauri B created by the gravitational pull of the orbiting planet. The effect is minute—it causes the star to move back and forth by no more than 51 centimetres per second (1.8 km/hour), about the ...
