The Sun is a nearly perfect sphere, with a diameter difference of only about 10 kilometers between its poles and equator. ​

Light from the Sun takes approximately 8 minutes and 20 seconds to reach Earth.

The Sun’s core temperature reaches about 15 million degrees Celsius, enabling nuclear fusion that powers the Sun. ​

The Sun’s gravity is 28 times stronger than Earth’s, anchoring the entire solar system.

The Sun is composed of approximately 70% hydrogen and 28% helium by mass. ​

The Sun rotates on its axis once every 25 days at the equator and approximately every 35 days at the poles. ​
