Astronomy: Moon

NASA explains the Harvest Moon. It's the full moon closest to the autumnal equinox. The Harvest Moon has the smallest difference in moonrise times between consecutive days.

Each month of the year has its own moon name. Which of them are song titles? "Harvest Moon" by Neil Young. "Pink Moon" by Nick Drake. "Hunter's Moon" by Thin White Rope. Incredibly, no one has written a song called "Beaver Moon".

So what do you call the big yellow moon that hovers over the horizon? I don't know. Big yellow moon? But why does it appear to be so big?

The "Moon Illusion" explained.

And what is a Killing Moon? It's a moon that will come too soon.
