### How is solar radius measured?

One of the best methods to determine the solar radius accurately is to measure it during planet transits (Venus or Mercury). The planet transits can even be used as an absolute calibration to determine the solar radius accurately.

#### What units are used in solar radius?

Solar radius is a unit of distance used to express the size of stars equal to the current radius of Sol: 1 R☉ = 6.955 X 105 km. One radius is about 10 times the average radius of Jupiter, 110 times the radius of Terra and 1/215th the distance of Terra from Sol.

#### What is the radius unit?

The radius is kind of the basic unit of a circle: its length is the distance from the center of a circle to any point on its circumference and it forms the basis for the radian. You can use the length of a circle’s radius to find its circumference (C=2πr), its area (A=πr2), and its diameter (d=2r).
