How many miles around is Earth at the equator?
No one knows for sure how many miles around Earth is.The exact distance of earth around the equator is 24,901.55 miles but if you measure through the poles instead it’s a little less. Earth has a bit of a bulge at the equator making it’s shape an ellipsoid. http://wiki.answers.com/Q/How_many_miles_around_is_Earth_at_the_equator http://wiki.answers.
The circumference of the earth at the equator is 24,901.55 miles (40,075.16 kilometers). But, if you measure the earth through the poles the circumference is a bit shorter – 24,859.82 miles (40,008 km). This means the earth is a tad wider 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).
