Supersized rocky planets are out there.

Given it's mass, age, and metallicity, it would be within the population II group (our sun is population I). Iron, et al, were obviously present in quantity when Kepler 10 formed (a star with Kepler 10's mass would not produce iron, it would have to be present at time of formation).

Good thing Kepler 10 is only 90% as massive as the sun. If it were as massive as the sun it would have become a white dwarf by now and the two planets in company would have been vaporized during the star's red giant stage a billion years ago.

These two planets are already older than the earth will ever be.

I wonder if this super earth is really the rocky core of an partially disintegrated jovian gas giant, the outter gaseous envelop having been stripped away either by solar radiation or by some giant impact.
