Pick a Peck of Pixels

A pixel, from Earth to the Moon, to the infinite and beyond

How big of a screen would you need to resolve the Apollo craft as a single pixel in an image which includes the earth and the moon?

Speaking of higher resolution, while I was contemplating Olbrich’s image I started thinking of what would be the size of Apollo space shuttle in the image. It would certainly be so tiny that it would be invisible to us. The next geekiest question would be: what should be the image’s minimum resolution to make the modules appear as a single pixel?
