The sun is a "new" star because it is fairly new compared to other stars that are billions of years older than our Sun.
The star that Earth orbits is the only star that we call the sun. That said, if you lived on a planet orbiting another star, you would probably call that star the sun.
There is no difference, its just that the sun is the closest star. And i am completely confused as to why u said YOUR sun....
No. The star is not vanished. When the star is born it is very small. Taking long time like 1 to 2 million years it get bigger and bigger. and in the last, it blasts. After it blasts it become a black hole or a new star. And the sun is in the middle of growing,so it is said that gravity of the sun pulles the earth near the sun and the earth will get burnt after 10 million years.
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.

At North Star they said that the Sun is 490 billion feet away from the earth
