Except the moon is acting as a (partial) reflector, and so is part of the optical system. So, really, you're limited to the temperature of the Sun, not to that

Except the moon is acting as a (partial) reflector, and so is part of the optical system. So, really, you're limited to the temperature of the Sun, not to that of the moon. So the conclusion is still potentially incorrect.
- klodolph 8y agoThat’s really stretching “optical system” if you include the moon. Sure, if we reshaped the moon into a giant mirror, we could use a lens light a fire using the “moon”.
