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.
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".
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.
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.
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.
Main sequence star: hydrogen-1.
Red giants: helium-4.
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.
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
Main sequence stars fuse hydrogen to helium. That means the fuel is hydrogen.
Stars use the element hydrogen for fuel, consuming it in nuclear fusion to produce helium and energy.
The main fuel for stars is hydrogen.
The primary fuel for all stars is hydrogen
No, red giants are generally older than main sequence stars, as red giants have no hydrogen left for fuel, and burn helium instead. where as Main Sequence stars burn hydrogen for fuel.

Hydrogen is the main source and Helium second.

gas, and other vibrate radiations.
main sequence stars all are burning though fuel at asteadyrate in there cores. with the proton+proton chain our sun is a main sequence star
A star that uses hydrogen as fuel is a main sequencestar.
main sequence stars of which colr use up their fuel supply in the shortest period of time? and why.
Hydrogen is being "burned" into helium.
Any star that it fusing hydrogen into helium is classed as a main sequence star.
Main sequence star: hydrogen-1. Red giants: helium-4.
