Stars are giant balls of hot gas – mostly hydrogen, with some helium and small amounts of other elements.
Jul 15, 2014 · A star is a luminous ball of gas, mostly hydrogen and helium, held together by its own gravity. Nuclear fusion reactions in its core support the star against gravity and produce photons and heat, as well as small amounts of heavier elements. The Sun is the closest star to Earth.
