At the Texas Meeting of the AAS this month it was announced that:
1. Nearly every star has one or more planets. Exoplanets/stars ~ 1.6/1
2. Double-star exoplanet systems appear to be not all that rare.
3. Ditto for pulsar-planet systems.
4. Exoplanet systems continue to defy pre-discovery predictions. Big
Given a minimum of 160 billion bound planets, and given a minimum of
200 billion unbound planetary-mass objects, is the capture of
planetary-mass objects by stellar-mass objects to form exoplanet
systems so unthinkable?
This process, of course, would primarily take place within relatively
dense star-forming regions, so the process is not easy to observe
directly, but the commonality of high-energy jet phenomenology also
taking place within star-forming regions is certainly suggestive.
One safe bet is that the surprises have only just begun.
