What is the main fuel in stars if any?

Answer 1

In our solar system both the gas giants Jupiter and Saturn, and the ice giants Uranus and Neptune (sometimes also called gas giants) are believed to have rocky cores, likely composed of silicates, ice, and possibly heavier elements like metals such as nickel/iron although their true composition is not well known. Above that are deep layers of metallic hydrogen. Their atmospheres are predominatly molecular hydrogen and some helium, with other compounds such as ammonia present in small amounts on Saturn. The ice giants Uranus and Neptune are so named for having much more icy compounds such as water, ammonia, and methane, and some nitrogen and hydrocarbons. The presence of methane in outer layers is thought to give Neptune its blue color.

Answer 2

Hydrogen
The main fuel of all all stars during almost all of their existence is the fusion of hydrogen into helium. Toward the end of their lives stars that are massive enough briefly (in astronomical terms) fuse helium into heavier elements and sometimes those heavier elements into yet heavier elements. But, those events happen only in large stars and only briefly. The answer is, "hydrogen".

Answer 3

Stars a giant balls of gas mainly hydrogen and helium. inside a star there are such temperatures that hydrogen fusion occurs making helium and when the star runs outta hydrogen it gets hotter and helium fusion occurs then carbon fusion etc etc. so ultimately it depends on the age of the star.

Answer 4

The "main" fuel for any star is Hydrogen, however there are varying quantities of other elements, any with an atomic weight less than Iron. When a star's nucleus is made up of mostly iron, which doesn't release the necessary energy when undergoing nuclear fusion, the star then collapses under its own weight.

Answer 5

Main sequence stars fuse hydrogen to helium. That means the fuel is hydrogen.

Main sequence stars fuse hydrogen to helium. That means the fuel is hydrogen.

Main sequence stars fuse hydrogen to helium. That means the fuel is hydrogen.

Main sequence stars fuse hydrogen to helium. That means the fuel is hydrogen.

Answer 6

The main fuel in stars is hydrogen, which undergoes nuclear fusion to form helium. This process releases a tremendous amount of energy that powers the star's luminosity and heat.

Answer 7

In most stars, the element Hydrogen fuses together to form Helium, a process that converts a tiny bit of mass into a whole lot of energy.

Answer 8

hydrogen

and helium

dunno cause stars don't only burn off those elements. yes mainly they do but what about the other gases like nitrogen and co2 and h2kc4kj3

Answer 9

Main sequence star: hydrogen-1.

Red giants: helium-4.

Answer 10

Stars use the element hydrogen for fuel, consuming it in nuclear fusion to produce helium and energy.
