what are stars made of?

Answer 1

Mostly hydrogen and helium, and a little bit (2 or 3 percent) of other stuff.

Answer 2

It depends on how old the star is. Stars are mostly hydrogen and helium, but the fusion process creates more compound elements. Eventually, when enough hydrogen is exhausted, the reaction becomes unstable and the star's size, appearance and dynamics change until a new stability is reached, as the helium is fused into lithium and heavier elements. The process repeats, as long as the star can achieve a new equilibrium each time, until about the iron stage, acording to current theory. Fusion beyond that is not possible, so the star collapses into a black or brown dwarf.

Answer 3

Stars are made up of gases mostly hydrogen and heluim gas formed froma cloud of interstellar dust and gas which spun qucikly collecescing getting hotter creating gravity then fusion started in the core. The star evolves over time depending on how much hydrengen, helium and other heavier metals are made during the fusion process. .

Answer 4

A star is a big mass of hot gases that has enough mass to achieve stellar ignition. A star usually at it's birth has 90 percent hydrogen, 10 percent helium, it can't have more than 1 percent of heavier elements. It burns through a process called nuclear fusion where lighter elements with a smaller amount of protons such has hydrogen fuse together to. If two hydrogen atoms fuse together, they each have one proton, they fuse and now, their is two protons which means, it has turned into helium, two helium atoms can fuse and turn to heavier elements. After all gases are turned to elements like iron, the star will reach the end of it's life cycle and grow ten times bigger than it's original size. If it was a big star, it is now classed has a red super giant, if it was a small star, it is now classed has a red giant. From here on, if it is huge, it can explode into a hyper nova and turn into a black hole or neutron star. When a smaller star dies, it explodes in a supernova. It will be turned into a dwarf star and it's last light will die out after words. After it ignites, it's life span depends on how big it is, if it is a huge star, it will fuse it's gas source faster into heavier elements and die out quicker, if it is smaller, even though it will have less gases, it will burn them slower and live longer. Through it's life, it goes through a number of colors based on how long it has left to live.

Blue Youngest 50,000-25,000 degrees Celsius
Blueish White 24,999-10,000 degrees Celsius
White 9,999-7,500 degrees Celsius
Yellow 7,499-5,000 degrees Celsius
Orange 4,999-3,500 degrees Celsius
Red 3,499-2,500 degrees Celsius

Answer 5

Mostly hydrogen and helium. There are also many other elements inside stars like lithium and nitrogen, but these elements are small in quantity.

Answer 6

I don't know, but I know each star is the same as our sun.

Answer 7

mostly hydrogen,part helium,and trace elements
