Size:
* Diameter: 1.392 million kilometers (865,000 miles)
* Radius: 696,000 kilometers (432,000 miles)
Mass:
* Solar masses: 1 (this is the standard unit for measuring stellar masses)
* Kilograms: 1.989 × 10^30 kilograms
* Earth masses: 333,000 times the mass of Earth
To put it in perspective:
* The Sun's diameter is about 109 times the diameter of Earth.
* The Sun's mass is about 333,000 times the mass of Earth.
* It is so massive that it accounts for 99.86% of the mass of the entire Solar System.
Interesting fact: The Sun is mostly made up of hydrogen (about 70.6% by mass) and helium (about 27.4% by mass).
