Everest Isn't the *Highest*?! The Earth's Bulge and the Real 'Tallest' Mountain

Did you know that while Mount Everest is undeniably the highest point above sea level on Earth, it’s actually not the furthest point from the Earth’s center? This is one of those facts that makes you go, “Wait, what?!”

Here’s the deal: most of us learn in school that Everest is the absolute pinnacle, and that’s true if you’re measuring from the surface of the ocean. But our beautiful planet isn’t a perfect sphere, you see. It actually bulges out quite a bit around the equator, kind of like if you spun a soft ball really fast and it flattened slightly at the poles and widened at the middle. This is due to the centrifugal force created by Earth’s rotation.

Because of this equatorial bulge, mountains that are closer to the equator get a bit of a head start, distance-wise, from the very core of the Earth. And that’s where Mount Chimborazo in Ecuador comes into the picture! Chimborazo is located very close to the equator, so even though its summit is a few thousand feet lower than Everest’s when measured from sea level, its position on that equatorial “belly” means its peak is actually about 2,072 meters (that’s roughly 6,800 feet!) further from the center of the Earth than Everest’s summit.

So, if you’re an astronaut trying to get as far away from the planet’s gravitational pull as possible, aiming for Chimborazo would give you a tiny head start! It’s a fantastic reminder that how we define and measure things can really change our understanding, even when it comes to something as fundamental as the ’tallest’ mountain. Pretty cool, right?
