Sun
The Sun is a massive, glowing sphere of hot gases at the center of our solar system. It produces energy through nuclear fusion, where hydrogen atoms fuse to form helium, releasing immense heat and light. This energy powers our climate, drives weather, and enables life on Earth. The Sun’s gravity keeps planets, including Earth, in orbit. Its surface temperature is about 5,500°C (9,932°F), and it influences space weather, which can affect satellite communications and power grids. As the closest star to us, the Sun is essential for sustaining life and shaping the environment of our planet.
