Sun's Radius
The solar radius (R☉) is the standard unit expressing the size of stars relative to the Sun, defined as 695,700 km (kira-kira 432,288 miles or about 109 times Earth's radius). It is formally defined as the distance from the Sun's center to the point where the optical depth equals 2/3, corresponding to the visible photosphere. The solar radius is a key parameter in stellar astronomy and astrophysics.
