Solar radius

Values of 1\,R_{\odot} Units
6.955 × 108 metres
6.955 × 105 kilometres
0.004652 AU

Solar radius is a unit of distance used to express the size of stars in astronomy equal to the current radius of the Sun:

1\,R_{\odot} = 6.955\times 10^8\,\hbox{m} = 0.004652 \hbox{AU}

The solar radius is approximately 695,500 kilometres (432,450 miles) or about 110 times the radius of the Earth, or 10 times the average radius of Jupiter. It varies slightly from pole to equator due to its rotation, which induces an oblateness of order 10 parts per million. See 1 gigametre for similar distances.
