Solar radii

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. It varies slightly from pole to equator due to Sol's rotation, which induces an oblateness of order 10 parts per million.
