By extension, the diameter is defined as twice the radius:
The typical abbreviation and mathematical symbol for radius is R or r.
The name comes from the Latin radius, meaning ray but also the spoke of a chariot wheel.
Earth radius is the distance from the center of Earth to a point on or near its surface.
Approximating the figure of Earth by an Earth spheroid, the radius ranges from a maximum of about 6378 km (3963 mi) to a minimum of nearly 6357 km (3950 mi).
The Schwarzschild radius was named after the German astronomer Karl Schwarzschild, who calculated this solution for the theory of general relativity in 1916.
The Schwarzschild radius is a parameter in the Schwarzschild solution to Einstein's field equations that corresponds to the radius of a sphere in flat space that has the same surface area as that of the event horizon of a Schwarzschild black hole of a given mass.
