Huh. Every day is a school day.
So my eldest tested me, asking what is wider, Australia or the Moon. I had understood that "the Moon is 1/4 the size of Earth", a relatively oft repeated fact. So I was like, the Moon must be.
So Australia is wider. By about 500km.
When they say, the Moon is 1/4 the "size" of Earth. They're talking about the diameter. It's 1/4 as wide. By volume, the Earth is around 49 times larger than the Moon! Much much much bigger!
I once knew that, maybe? Now I surely do.
