We built a laser frequency comb to assist in measuring the stellar wabbling caused by its planets. The velocity of the stars that are thousands of light years away from us, can be measured down to 30 cm/s accuracies. The system was tested in the NASA IRTF telescope and W.M. Keck Observatory, Hawaii.
