If a star has one detectable planet, then the odds are about 50-50 that another planet will be detected after several additional years of monitoring. For a variety of reasons, multiple-planet systems are scientifically more valuable than single-planet systems. In particular, a multiple-planet system (such as GJ 876) tells a fascinating dynamical story, which in turn yields valuable information about the formation and evolution of the planetary system. Obtaining radial velocities is hard, expensive work. It’s a whack move when some player-hater jacks your hard-earned data to get a roll on their own opportunisitic Doppler velocity monitoring program.

But as we wait for breakthroughs in space-based hardware, planetary detections keep occurring. And astronomer Greg Laughlin (University of California, Santa Cruz) has a thought on what we might find using today’s technologies.
