Fusion in the sun converts Hydrogen into Helium, so finding out how much Helium is in the Sun can determine how old it is.
If the spectrum of a star shows the same absorption lines as the sun than you know that the star has the same composition as the sun. This means that the star is made of the same elements as the sun.
yes the star in the sky small sun and the star one of composition of sun that giving a light on night to help .and on day their is greater light is the sun it helpful .thank you get all about on google.com
That would be difficult to explain. -- The Sun IS a star. -- It IS in my solar system. -- It's the ONLY star in my solar system. -- So the sun is THE star in my solar system.
Yes, in comparision with the rest of the universe, our Sun is a relatively young star.
Since it has about twice the mass of the Sun, you can expect it to be relatively young. Such massive stars burn out fairly quickly (for a star).
No. It is a typical star of the main sequence for its mass. The composition and mass of each star determines its color, size, and life cycle.
no a bulet can,t go that far
A gas giant is similar in composition to the Sun. The Sun is much bigger than the gas giants and it is a star not a planet, of course.
The proof that the sun is a star lies in its characteristics and behavior. Like other stars, the sun is a luminous sphere of hot gas that undergoes nuclear fusion to emit heat and light. Observations of the sun's spectrum, composition, and energy output confirm its stellar nature. Additionally, studies of other stars in the universe show that the sun shares similarities in its properties, further supporting its classification as a star.
Though no authority on this subject I would guess that color would suggest that our sun is a relatively young star. Yellow being a much younger star than say the blue or red stars which are much hotter, so suggesting that they are much older. There are some who would suggest that our sun has used up all of its energy and is cooling down making it much older that I first suggested.
because they will have the same elements in the atmosphere...
No, the sun is not the first star made. The sun is a relatively young star in the universe, formed billions of years after the first stars. The first stars in the universe were primarily made of hydrogen and helium.
