What is solar radius?

The solar radius is a measure of the size of the sun. It is defined as the distance from the center of the sun to its surface, and it is approximately 696,340 kilometers (432,687 miles) long. The sun’s radius is used in various astronomical calculations, such as determining the amount of energy that the sun emits and calculating the distance between the sun and other celestial bodies. Additionally, it is used as a reference point for comparing the size of other stars. The solar radius is an important astronomical parameter that helps scientists to understand the structure and behavior of the sun.
