this potographer had a few-seconds' window to capture the ISS against

the moon:

The ISS appears big because it is close to us. I was curious to see what it would look like if it was in orbit around the moon. Turns out, it would be one-tenth the size of even a single pixel.

I edited the image to show this: http://aprs.org/ISS-moon-picture.png
