what are stars made of?

Answer 1

Mostly hydrogen plasma. Plasma is made up of the nuclei
of atoms with the electrons stripped away due to the extremely
high temperature. So it's mostly protons, sometimes in pairs which are helium nuclei and a lot of neutrons. The surface temperature is about 6000° C or 11,000° F while the inner core is
15,000,000° C or 27,000,000° F and has pressure 340 billion times Earth's air pressure at sea level which is so intense that nuclear reactions take place.

Answer 2

It depends somewhat on the star, but most stars are made primarily of hydrogen in the plasma state, which an ionized gas. Inside the star, hydrogen is being fused into helium, which is what causes it to produce light and heat, so the star contains a significant amount of hydrogen as well.

At the end of its life cycle, the star runs out of hydrogen, and begins fusing the helium into heavier elements. So as the star dies, it begins to contain heavier elements like chlorine, and even carbon and iron. (In astronomy, all elements heavier than helium are called "metals.") Stars that were born relatively recently started their lives containing some of these heavier elements, because the interstellar medium had been enriched by older stars that died, but they still contain mostly hydrogen.

Answer 3

Basically, stars are big exploding balls of gas, mostly hydrogen and helium. Our nearest star, the Sun, is so hot that the huge amount of hydrogen is undergoing a constant star-wide nuclear reaction, like in a hydrogen bomb

Answer 4

Mostly Hydrogen ions, which when hot enough fuse into helium ions. As it gets hotter the newer ions fuse to make other elements under the metals side of things, getting bigger until they reach lead. Lead is the most stable of the metals, and not even the hottest stars are capable of fusing lead to a heavier form.

Answer 5

Hydrogen and helium are the main components of the star. And stars produce energy because of the fission of these gases.

Answer 6

Mostly Helium and Hydrogen

Answer 7

Gas, mainly
The 1st two elements of the whole scheme of things - hydrogen & helium.
Plus bits of other elements so produced.
Great things, stars. We would not be here without our local one.

Answer 8

Hot gas. And most stars are composed of mostly hydrogen gas.

Answer 9

Mostly Hydrogen.

Answer 10

Hydrogen on surface and several other elements
in the interior, like molten rock. Similar to our sun.
