The distance around the equator of the planet is 24,901.55 miles. Measurements taken through the poles, however, result in a smaller radius of 24,859.82 miles.
Because of how the Earth is shaped, there are small differences in its circumference. The Earth is an oblate spheroid rather than a perfect spherical. It is faster to fly around the Earth by travelling via its poles rather than around its circumference because of its shape and variations in circumference.
Other planets in the solar system, such as Jupiter, which has an equatorial circumference of 279,118 miles, and the sun, which has an equatorial diameter of 2,720,000 miles, are far larger than the Earth.
