What are stars mainly made up with?

Answer 1

When stars first form and fusion takes place the star is almost totally Hydrogen. During fusion it turns Hydrogen to Helium. Once all the Hydrogen is used up it will then start to fuse Helium and so forth and so on. Depending where in the life cycle the star is will denote its composition.

Answer 2

Stars are mainly composed of hydrogen (about 74%) and helium (about 24%). The rest of a star's composition consists of trace elements like carbon, oxygen, and nitrogen. These elements are created through nuclear fusion processes that occur within a star's core.

Answer 3

99% of the Universe is plasma. Additional the matter of the universe consists of dark energy (70%), dark matter (25%), hydrogen and helium (4%) and and rest of neutrinos stars and other heavy elements.

Answer 4

The part of a star we see (or would see, if we were close enough) is called its photosphere and is Hydrogen and Helium gases. Large planets, such as Jupiter and Saturn, are ALSO encased in Hydrogen/Helium atmospheres, but the aren't big enough to start nuclear fusion, so they aren't stars.
