That is pretty interesting. Surface gravity of 2G or so, and average
temperatures estimated at 0-40 C. It'd be really interesting to see
what has evolved there, if anything.

As it happened, I noted that on the same day that this somewhat
Earthlike planet - orbiting a small, cool, red sun, and with a high
surface gravity - was discovered, there was also news about a new
mineral discovered in Serbia. Neither green nor radioactive, it did
correspond to a chemical formula given as a throwaway line in
"Superman Returns" for Kryptonite, however.

Krypton *and* Kryptonite discovered on the same day?
