The Sun

Top of Page

Without the Sun, the Earth would be a lifeless ball of rock and ice. The Sun warms our planet, creates our weather, and gives energy to plants providing food and energy to support life on Earth.

The Sun is a large ball of gas consisting mostly of hydrogen and helium. The Sun is about 109 times larger than Earth.

Scientists estimate that the temperature at the center of the Sun is about 15 million degrees celcius. This is similar to exploding a hydrogen, or nuclear, bomb. Large explosions on the Sun's surface cause solar flares that shoot up high into space. The surface temperature is about 4000 degrees celcius.

Energy released from the Sun radiates in all directions, reaching the Earth and other planets. The further the planet is from the Sun, the less energy it receives.
