Changeable moon

Yes. This is because the many monocular cues for depth make it look larger.
But since we know it can't be, we feel it's closer.
But I don't know it can't be. Until getting into this thread, I thought that an optical effect of the atmosphere really did make it "larger" by magnification.

Here's one of my favorite factoids about bserving the Moon. Ask yourself (or someone else) this question - how far away from your eye, would you have to hold a US dime coin, in order to just block the full Moon? Rolfe, I assume you probably know about how big a dime is - it's the smallest US coin.

Go ahead, come up with an answer, without actually trying it. Just imagine it.

Most people will say something like two feet, or less than a meter - something they can easily reach with their arm. The answer is six or seven feet - two meters.

Yes, well. if you actually look at my posts, you'll see that this is the site I've been trying to work my way through. And it obviously isn't a simple, easy-to understand explanation. I just got to the bit about all objects being affected, and the illusion also involving the apparent size of objects on the horizon.

I quoted it too. But I struggled to follow it. Any chance of a layman's summary?
