Claims

  1. From microlensing data for 2002–2007, covering orbits 0.5–10 AU from their stars and resting on 10 planet detections, the study estimates that 17% of stars host Jupiter-mass planets and that cool Neptunes and super-Earths are more common (52% and 62% per star), concluding that stars are orbited by planets as a rule rather than the exception.
    "We conclude that stars are orbited by planets as a rule, rather than the exception."
