Kepler found one very, very strange case:
http://www.theatlantic.com/science/archive...-galaxy/410023/ In a nutshell, while Kepler was observing it, the star (larger and brighter than the Sun) exhibited four dimming events that took place at irregular intervals, blocked a lot more light than a Jupiter-sized planet would block, and had a "shape" that varied in all four cases and did not resemble a planet. This case is attracting some wild speculation… in fact, it is seemingly certain that something wild must be going on; it's just a matter of which wild scenario is the correct one. If I had to throw my hat in the ring, I'd guess that a distant collision and breakup has placed big swarms of matter into a very long-period orbit. But there's no hypothesis that's been offered that doesn't seem problematic. |

I was browsing the extreme exoplanets list on Wikipedia and stumbled upon this; it has to be a measurement mistake, right? https://en.wikipedia.org/wiki/K2-22b.
It would be denser then the element mercury and have around 70 G surface gravity, if true! Like that old Hal Clement novel.... NASA page here: http://exoplanetarchive.ipac.caltech.edu/c...ONFIRMED_PLANET |
