Earth's Polar Radius
The Earth's polar radius is the distance from the center of the Earth to the North or South Pole, approximately 6,356.8 kilometers.
History/Origin
The fact that the Earth is an oblate spheroid, flattened at the poles, has been known since the 18th century. Modern measurements are made with high precision.
Current Use
The Earth's polar radius is a key parameter in geodesy and is used to define the Earth's shape and gravitational field.
Gigameter
A gigameter is a unit of length in the metric system equal to 10^9 meters.
History/Origin
The prefix "giga-" for 10^9 was adopted by the CGPM (General Conference on Weights and Measures) in 1960.
Current Use
The gigameter is used for measuring interplanetary distances, for example, the distance between Earth and Mars.
