How long is a round around the Earth?

Wow, ever think about just, like, walking around the Earth? How long would that even take?! It’s crazy, right? Apparently, it depends on where you go. The Earth isn’t a perfect sphere, it’s kinda squished, more like a mandarin orange than a basketball. So, if you were to walk around the equator – which, let’s be honest, who’s got time for that? – it would be about 40,075 kilometers. That’s like, 24,901 miles! I once drove from New York to LA, and that felt like forever. Can you imagine? But if you were a super hardcore polar explorer type, and you trekked around one of the poles, it’s a bit shorter. Like 40,008 km, or 24,860 miles. Not a huge difference, but still, something to think about. Isn’t that wild? It’s like the Earth is saying, “Hey, take the scenic route…or the slightly less scenic route.”
