Earth isn't actually a perfect sphere.

Although we often think of and depict the Earth as a perfectly round globe, Earth's shape is what's known as an oblate spheroid. Because of the force caused by Earth's rotation, the equator bulges slightly outward. In fact, if you were to travel around the equator, you'd be traveling about 43 km more than if you were to travel around the Earth from pole to pole.

This leads to the strange fact that, although Mount Everest is the tallest mountain on Earth, the point furthest away from Earth's center is actually Mount Chimborazo in Ecuador. Additionally, because the force of gravity is affected by your distance from the center of the Earth, you would weigh slightly less on the equator than at one of Earth's poles.
