The Sun!
The Sun is the star that is at the center of our solar system. The temperature at the surface of the Sun is nearly 5504 degrees celcius! The Sun's energy is the most important source of energy for life on Earth and it is about 4.6 billion years old! The mass of the Sun mostly contains hydrogen and helium with heavier elements such as oxygen, carbon, neon and iron in smaller quantities. There are even spots on the Sun called sunspots that can blow up and mess with our phone signals. What might shock some people is that it is already halfway through its life. Scientists say that this yellow dwarf star will die, the Sun will become a red giant star and it will become so large that it would engulf Mercury, Venus and maybe Earth too.
