According to NASA, Earth's radius at the equator is 3,963 miles (6,378 kilometers), while the radius at the poles is 3,950 miles (6,356 km). Therefore, the diameter of Earth through its center is ...

At the equator, even when the air is calm, the planet and the atmosphere above it are actually moving at over 1,000 mph (1,600 km/h), Barnes said. This movement follows Earth's direction of spin ...

(Added to the U.S.: 650 square miles.) By U.S. measurements the earth’s radius at the equator is 3,963⅓-miles. Too small, said Izotov; he calculated that in its thickest section the radius is ...

Jupiter’s radius is over 11 times the equatorial radius of the Earth, according to AZ Animals. The largest exoplanet (not including brown dwarfs, which are failed stars) is ROXs 42Bb ...

Multiplying this angular acceleration by Earth’s radius yields linear acceleration at the equator: Therefore, for one second of full-throttle acceleration, the change of the Earth’s velocity ...
