The Sun is a 4.5 billion-year-old yellow dwarf star – a hot glowing ball of hydrogen and helium – at the center of our solar system. It’s about 93 million miles (150 million kilometers) from Earth and it’s our solar system’s only star. Without the Sun’s energy, life as we know it could not exist on our home planet.

22 de ene. de 2013 · NASA. Jan 22, 2013. The sun and its atmosphere consist of several zones or layers. From the inside out, the solar interior consists of: the Core (the central region where nuclear reactions consume hydrogen to form helium. These reactions release the energy that ultimately leaves the surface as visible light. ),
3 de jun. de 2024 · The Sun contains almost ALL of the material in our solar system. 99% of it. All the planets, asteroids and comets add up to less than 1% of the total. The Sun is so far away that it takes light about 8 minutes and 20 seconds for it to get to us – and light is the fastest thing in the universe.
