What is the diameter of the earth?
The diameter of the earth at the equator is 7,926.41 miles (12,756.32 kilometers).
If you measure the earth through the poles the diameter is a bit shorter - 7,901 miles (12,715.43 km).
Thus the earth is a tad wider (25 miles / 41 km) than it is tall, giving it a slight bulge at the equator.
This shape is known as an ellipsoid or more properly, geoid (earth-like).
