How big is the Moon?

The radius of the moon is about 1740 km.

The diameter is therefore twice that:

or 3480 km.

Canada's is 5,514 kilometers wide.

That means the whole moon would fit inside Canada, if it fell straight through, like a basketball.

What about the surface of the moon compared to Canada?

surface area of a sphere = 4 times PI times radius times radius

or
area = 4 * 3.14 * radius^2

area of moon = 4 * 3.14 * 1740 * 1740

= 38,026,656 km

The surface area of Canada is 9,900,000 kilometers so the moon's surface is about 4 times bigger than Canada's total amount of land if you were to explore all of it.

That's very big!

Thanks for the question, Kendra!
