Not really. A supernova is when a massive star has used up all of it's hydrogen and because of the immense gravitation, the star is unable to support itself, and violently explodes as a supernova [See related]
A star is not really dead until it no longer emits energy. because of the size of the stars and the amount of latent energy, they can radiate energy for billions of years.

∙ 14y agoIf you can see them, they are not dead.
10% of stars are off of the main sequence which could be a cutting off point, but a star that is not on the main sequence will still radiate energy into space for billions of years.

∙ 14y agoYes, they may have died a long time ago. Because sight can only travel so fast and the stars are so far away, they may have possibly died thousands, millions, maybe even billions of years ago.

∙ 8y agoNo. The sun is a fairly ordinary star. It only appears bigger and brighter than others because it is much closer to us.

If it was dead, you would not be alive!

I'll have to say that Earth's nearest star is the Sun............... I know for sure that mercury's closest star is the Sun ( The Sun is a Star) Yes the nearest star is the sun
How many stars are there in our solar system?
Our sun is actually a small star, tons of stars are way bigger than our sun. One. Each star is a sun.
Why is the sun considered ''the sun'' and not a star?
Nope. The sun is considered a star.
Is a the sun a dwarf galaxy?
It is impossible for the sun to be a dwarf galaxy because the sun is a star. But if you're asking if it's a dwarf star, then no, otherwise we'd be dead.

It gives off heat. If there was no sun we would be dead.
What is the core of a sun like star called when its dead?

No. The sun is a main sequence star. A black dwarf is the remnant of a dead star that has cooled. The universe is not old enough for this to have happened yet.

What do you think the difference is between a black dwarf and a supernova explosion?
A black dwarf is a dead white dwarf. By dead, I mean a star that no longer burns. A white dwarf, in turn, is a dead "moderate" star (a star like our sun). So a black dwarf is a star that's died twice, with mass not much higher or probably lower than that of our sun. A supernova, is the "death" of a star that's really huge. By huge, I mean it has a mass that's considerably higher than that of our sun. That kind of star doesn't turn into a white dwarf. Rather, it becomes either a neutron star (pulsar or non-pulsar) or a black hole.
