The Sun is one of the heaviest objects in our solar system, and it weighs more than 2 nonillion pounds. This is about 333,000 times the mass of the Earth!
Our Sun is made up of a mixture of 73% hydrogen and 25% helium. These elements are converted into energy through nuclear fusion reactions in the center of the star.
This star is a near-perfect ball of hot plasma, heated to incandescence by nuclear fusion reactions within its core. This is where the majority of our solar system’s energy comes from!
Its radius is 1.4 million kilometers and its diameter is 109 times that of the Earth. This makes the sun one of the largest stars in the universe!
The Sun is about halfway through its life, and will eventually expand into a red giant star. It will then collapse in on itself and become a white dwarf.
The sun has a large amount of gravity, which keeps our planets in orbit around it and prevents them from flying off into space. Without the sun’s gravity, our planets would be free to move out of our solar system!
The stars that are closest to us are called main sequence stars, and they are made up of a combination of hydrogen and helium. The majority of the star’s energy is generated through the conversion of these two elements through nuclear fusion.
