The nearest star to Earth, and the centre of our Solar System.
The nearest star to Earth, and the centre of our Solar System. Every second the Sun loses 4 million tonnes of mass through nuclear fusion, releasing enough energy to create a core temperature of about 15,000,000°C, and a surface temperature of around 5500°C. The Sun is ultimately the source of almost all energy on Earth.
