The solar radius is approximately 695,500 kilometres (432,450 miles) or about 110 times the radius of the Yird, or 10 times the average radius o Jupiter. It varies slichtly frae pole to equator due to its rotation, which induces an oblateness of order 10 pairts per million. See 1 gigametre for similar distances.
The SOHO spacecraft wis used to measure the diameter of the Sun bi timin transits of Mercury athort the surface during 2003 an 2006. The result wis a measured radius of 696,342 ± 65 kilometres (432,687 ± 40 miles).
