It's exactly the same as a "sunny 16" shot on earth. That is 1/ISO @ f16; or 1/100 of a second shutterspeed at f16 if you are using ISO 100.

What is lighting the moon?
The sun.

Is the sun about the same distance from the earth or moon?
Yes.

Does the sunny 16 rule work on a nice day on earth?
Yes.

Then because it's the same light then it's the same exposure.

Cool! I thought atmosphere etc would affect it

Don't be silly, there's no atmosphere on the moon.

Aren't you still shooting throught the earth's atmosphere?
