I actually had a hard time believing this, since the moon seems to be so much bigger when it's near the horizon. True to science I set up an experiment with a stick and a caliper - I could look from one end of the stick to the caliper fastened at the other end, and slide it so that the circumference of the moon would exactly fit. I could then look at the moon both when it was high in the sky, and when it was just above the horizon. Lo and behold - they were the exact same size, even though it didn't look that way at all. What I learned is that you can't always trust your senses.
