A penny at a temperature high enough to radiate the same amount of energy as the entire surface of the sun, would be at a far higher temperature than the sun.

- Dylan16807 8y agoIf you surround the penny with sun with no gaps, all the light hits the penny. If you add more sun, you add gaps, and the amount of light hitting the penny stays constant. It never has more than one penny-surface-area of light hitting it, so it never has to get hotter than the sun.
