Claims
-
Close-in super-Earths cannot have formed where they are now and require substantial inward movement of solid material; migration is an inevitable consequence of planet formation. With present-day technology, an observer elsewhere would detect only Jupiter in the Solar System.

-
The Solar System is unusual at roughly the 1% level among Sun-like stars: about 10% of Sun-like stars have gas giants, and only about a tenth of those resemble Jupiter (beyond 2 AU, eccentricity below 0.1). At least 30–50% of main-sequence stars have close-in planets smaller than about 4 Earth radii, and fewer than 8% of planetary systems have their innermost planet on an orbit as wide as Mercury's.
