Where Is the Earth Widest?

The Earth is widest at its Equator. The distance around the Earth at the Equator, its circumference, is 40,075 kilometers (24,901 miles). The Earth's diameter is also wider at the Equator, creating a phenomenon called an equatorial bulge.

Why is Earth wider at Equator?

The Earth is wider at the equator than from pole to pole, mainly because the centrifugal forces of its rotation make it bulge outwards. Satellites can measure its average shape using gravity and altitude data. Over most of the past 20 years, these observations showed that overall the Earth is becoming more round.

What is the widest diameter of the Earth?

As a result, the latest measurements indicate that the Earth has an equatorial diameter of 12,756 km (7926 mi), and a polar diameter of 12713.6 km (7899.86 mi). In short, objects located along the equator are about 21 km further away from the center of the Earth (geocenter) than objects located at the poles.
