The solar radius is approximately 695,700 kilometres (432,300 miles), which is about 10 times the average radius of Jupiter, 110 times the radius of the Earth, and 1 / 215th of an astronomical unit, the distance of the Earth from the Sun. It varies slightly from pole to equator due to its rotation, which induces an oblateness in the order of 10 parts per million. (See 1 gigametre for similar distances.)

What is the solar radius of the sun? Let's have some stream of consciousness first.
To answer this question, we should know that: The solar radius is approximately 695,700 kilometres (432,300 miles), which is about 10 times the average radius of Jupiter, 110 times the radius of the Earth, and 1 / 215th of an astronomical unit, the distance of the Earth from the Sun. So, the answer is approximately 695,700 kilometres ( 432,300 miles ).
