Most stars are made by a fusion of hydrogen and helium. There are also rocks, dust and other gases present in the composition of stars. A star is made when gravitational forces fuse these compounds into what appears to be like a big hot orb.
When stars form they are composed of about 70% hydrogen and 28% helium, as measured by mass, with a small fraction of heavier elements such as iron.
A star is made from flaming gases or blazing balls of fire and is located in our solar system. An example is the Sun which produces enormous heat; as well as numerous atoms. The atoms are produced in the explosive environment of the flaming gases.
Stars are made of plasma, which is an ionized (electrically charged) gas, held together by gravity. Stars are comprised mostly of hydrogen, which they convert into helium via nuclear fusion.
Stars are mostly made of gas such as hydrogen and helium. The nearest star to Earth is the Sun. Stars are composed of approximately 73% hydrogen, 25% helium, and 2% of all the other elements.
