Mean Radius of Sun is an astronomical constant. It is defined as the Sun's physical center to the surface. The mean radius for Sun is approximately equal to 69,50,000 meters (6.95 x 10^6 m). This is roughly 6950 kilometers (km) or 3,960 statute miles. This length is also used as a unit of distance.

The International Union of Geodesy and Geophysics (IUGG) defines the mean radius R1 to be, R1 = (2a + b) / 3. Here, a is the Equatorial radius which is the constant value of 6,378.1370 km and b is the Polar radius which is equal to 6,356.7523 km.
