What makes up all stars

Answer 1

All stars are primarily made up of plasma, which is a hot, ionized gas composed of hydrogen and helium. These two elements are the most abundant in stars, with hydrogen making up about 74% of their mass and helium about 24%. The remaining 2% consists of trace amounts of other elements such as carbon, oxygen, nitrogen, and heavier elements produced through nuclear fusion in the cores of stars. These elements are crucial for the processes that power stars and give them their various characteristics.
