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 (लगभग 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.
