What Is the Polar Circumference of Earth? | Reference.com

The circumference of the Earth, measured along a line of longitude, is just under 24,860 miles. Earth’s equatorial circumference, however, is somewhat greater, at slightly less than 24,902 miles. This difference is a result of the planet’s rotation. Keep Learning.

Earth’s Equatorial Circumference Is Greater Than Its Polar

More Cool Science Facts. The circumference of Earth at the equator is about 24,902 miles (40,075 km), but from pole-to-pole — the meridional circumference — Earth is only 24,860 miles (40,008 km) around. This shape, caused by the flattening at the poles, is called an oblate spheroid.

How Big Is Earth? – Radius, Diameter and Circumference

Radius, diameter and circumference. Earth’s polar radius is 3,950 miles (6,356 km) — a difference of 13 miles (22 km). Using those measurements, the equatorial circumference of Earth is about 24,901 miles (40,075 km). However, from pole-to-pole — the meridional circumference — Earth is only 24,860 miles (40,008 km) around.

How does the Earth’s polar circumference compare to its

Related Questions More Answers Below. Because the Earth rotates, centrifugal forces push the equator outward. This is referred to as the Earth’s oblateness. This results in the Earth having a polar circumference of 40008 km, and an equatorial circumference of 40075 km, a difference of 67 kilometers. Other planets have more pronounced oblateness,

What is the circumference of the Earth – Answers.com

Jan 25, 2019 · The polar circumference of the Earth is about 40,008 km (24,860 m). More Precisely: Earth is not a perfect sphere, but is “flattened” at the poles. Its shape is described as an oblate spheroid. So, the Earth’s circumference is about 68 km (41 m), larger around its belly than around its poles.

Earth’s circumference – Wikipedia

Earth’s polar circumference is almost exactly 40,000 km because the metre was originally calibrated on this measurement (1/10-millionth of the distance between the poles and the equator), which is almost exactly 21,600 nautical miles (being defined as one minute of a degree – i.e. 360 multiplied by 60).
