How big a planet do we have to have to create 267 GPa pressure at the center? Is the temperature in the center of a planet necessarily too high for superconductivity ? I'm trying to imagine a big enough, cold enough planet with a superconducting core. Would such a planet have peculiar enough properties to be visible from lightyears away?
