Supersized rocky planets are out there.

Is that a case of selection bias (whereby higher-mass planets are easier to spot using current detection methods)?

I believe the result doesn't come from counting the earth sized planets dicovered. So there is no selection biase on that count. Instead result comes from the observation that in majority of solar systems thus far discovered, it would be dynamically very difficult for any earth sized planet to survive for long period without either colliding with the parent star or be jetisoned out of the system.

Thanks for the info - I used to follow exoplanet research and discoveries closely, back when they were still fairly novel. Back then as you know, the search methods (e.g. radial velocity) selected for high-mass planets.

Fixed that for you.

Actually, if the planet has 17 times earth mass, but 2.4 times earth radius, than its surface gravity would be about 2.8G.

It would certainly be possibly for a weight lifter to stand or do squats on that planet.

I doubt that applies to any of us involved in that subthread.
