Seeing the size of Earth as it really appears from the surface of the moon reminds me of this wallpaper that I grew up with in my room as a child. I always assumed it was an actual image, but in reality the Earth appears about 1/20 the size and Earth would never phase in shadow from north to south under any circumstance! (I missed that obvious flaw as pointed out by Paul Neave). I beleive they still sell this wallpaper as I still see it around occasionally at stores and other public spaces (no pun). In addition to this image, you also see the Earth from moon shots taken while in- moon-orbit which also gives the Earth a far larger appearance… but I suspect that some good zoom lenses were likely utilized to get those looks as well.
