All stars are composed mostly of hydrogen. The star fuses hydrogen into helium. The helium cannot escape the start until the end of the star's life cycle. Thus a middle-aged, medium sized star will be comprised of hydrogen and helium. As the star ages, it may start to fuse helium at its core into carbon. At this point it will likely expand into a red giant star, and thus would no longer be yellow.
What else can I help you with?
The sun is composed of what?
The sun is composed mostly of hydrogen (about 74%) and helium (about 24%), with smaller amounts of other elements like oxygen, carbon, neon, and iron. It generates energy through nuclear fusion reactions in its core.
The sun is composed mostly of what?
The sun is primarily composed of hydrogen (about 74%) and helium (about 24%). These two elements make up the vast majority of its mass, with traces of other elements present.
Which planets are mostly made of atmosphere?
Jupiter and Saturn are mostly made of atmosphere, with Jupiter's atmosphere consisting mostly of hydrogen and helium, while Saturn's atmosphere is also primarily composed of hydrogen and helium, with traces of other elements.
What are the Sun's main atmospheric gases?
The Sun's atmosphere is primarily composed of hydrogen and helium. These two gases make up over 98% of the Sun's total mass. Other gases present in smaller amounts include oxygen, carbon, neon, and iron.
Is the sun mostly helium?
The Sun is mostly composed of hydrogen (about 74% by mass) and helium (about 24% by mass). These two elements are present in the Sun's core, where nuclear fusion reactions take place, releasing energy in the form of light and heat.
What is something mostly hydrogen some helium?
A star is mostly composed of hydrogen and some helium. The fusion of hydrogen into helium is what produces the energy and light that stars emit.

Is Saturn a gas plant or a not?
Jupiter and Saturn consist mostly of hydrogen and helium, yes it is.
What is the composition atmosphere in Uranus?
it's mostly composed out of methane, hydrogen molecular and helium.
What are elements called that make up a star?

What major gaseous substances are in Jupiter and Saturn?
Jupiter and Saturn primarily consist of hydrogen and helium, with trace amounts of other gases such as methane, ammonia, and water vapor. These gas giants have thick atmospheres that are mostly composed of hydrogen and helium.
What element are stars mostly composed of?
hydrogen,All stars are composed primarily of hydrogen. Stars can also contain some other elements such as helium, but hydrogen accounts for the majority of a star's composition.
What kind of rock makes up Saturn?
Saturn is a gas giant planet composed mostly of hydrogen and helium. It does not have a solid surface made of rock like Earth. The outer layer of Saturn is mostly composed of hydrogen and helium with trace amounts of other elements.
