Solar radius


Solar radius

In astronomy, the solar radius is a unit of length used to express the size of stars. It is equal to the current radius of the Sun. Its value is:

:1,R_{odot} = 6.960 imes 10^8,hbox{m} = 0.004652,hbox{AU} (Astronomical unit).

The solar radius is approximately 432,450 miles (695,500 kilometers) or about 110 times the radius of the Earth, or 10 times the average radius of Jupiter.
