The sun's diameter is used to measure the diameters of other stars. For example, the behemoth star VY Canis Majoris has a diameter between 1,420 to 2,200 (= 2 to 3 billion km) times greater than the Sun's own diameter.

The Sun's diameter is used to measure the diameter of other stars. The Sun's diameter is represented by the symbol D and is equivalent to 1,392,400 kilometers.

Solar radius[edit]

Alternatively, the Sun's radius can be used as a unit of measuring distance rather than the diameter. However, when the Sun's radius is used instead, the unit will be used to measure the radius rather than the diameter, so the star's measured size will remain the same when measured by solar diameter. The solar radius is equivalent to 696,200 kilometers and is represented by the symbol R.
