The same chemicals as here on earth, in varying amounts. Our bodies are carbon, hydrogen , oxygen... the planet itself has many rocks eg limestone, which is calcium carbonate , and a lot of iron, for example the core is iron. The sun is helium and hydrogen for the most part. The moon is made of the same stuff as earth which is part of the evidence that leads us to believe it was formed by a large meteorite smacking into the early earth. Venus is a rocky planet with an atmosphere of carbon dioxide adn sulphuric acid. Jupiter is made of hydrogen, helium and ammonia. All the elements that exist have been formed by reactions inside stars that have lived and died, spreading their mass all over the universe when they go supernova. Older stars contain heavier elements (ie further down the Periodic Table).

The sun consist mainly of hydrogen which makes up about 75% and helium about 25%. Helium is produced in the sun's core as it burns hydrogen. There are smaller amounts of other materials, but these are less than 1%. There is no element which makes up about 10% of the sun.
gases as hydrogen and helium

Hydrogen makes up about 75% of the sun's mass. It is the primary fuel source for the sun's nuclear fusion reactions that produce energy.
The brain is an electro-chemical organ powered by the food you eat. The energy in the food you eat comes from the Sun. Thus it is the Sun that makes the brain function.
