The sun will turn into a red giant, then into a white dwarf surrounded by a planetary nebula. This will take billions of years. The white dwarf is basically the ash of a star. It’s a hot glowing remnant that no longer has nuclear fusion and so it’ll just glow for trillions of years slowly losing heat and light until it becomes a cold lump of carbon. The inner solar system will most likely be wiped out during the red giant phase as the sun will expand tremendously in size eventually reaching somewhere between earth and mars’ orbit.

    Fun fact, while the earth will almost certainly be engulfed by the red giant phase of our sun, it will not be immediately consumed. A floating lump of rock will exist and continue to orbit the center of mass for millions of years inside the sun.

    A problem i see with your theory is that the outer layers of the sun are plenty hot enough to melt rock and as soon as that happens the rock is probably just going to become part of the plasma making up the sun’s atmosphere.

    Of course, the sun isn't special. We have about 5 billion more years.

    You wrote million instead of billion.

    I mean, I didn't. It say 5 billions and the comment is un-edited. But thanks?

    You should find a new hobby like googling because it would tell you the sun will burn out in ~5 billion years

    Questions are a good thing and preferring to get answers from humans instead of machines is a good instinct. Less harshness and more humanity makes the fediverse a better place.

    The correct thing would have been to look it up and share the information with the fediverse, this is a basic fact question not a matter of opinion or discussion

    This is just pure laziness.

    I agree with the sentiment OP should have just googled this, but we dont know who this person is. what if they are a child? Who says basic questions arent allowed? am I missing something?

    I'm neutral on this kind of question, I just don't answer in the hopes someone else does and just move on

    If they’re a child all the more reason for everyone to tell them to google stuff

    A child won't necessarily know how to filter the slop from actual correct info. At least in a forum you'll more than likely have a bunch of voices stating the facts and a few stating untruths. Unless they're asking for some arcane knowledge that only a dozen people on the planet understands they're probably better off on a forum.

    You might want to sit down for this, but the sun is also a star. We’re just really really close to it.

    One proposal suggests that the universe will entirely run down eventually. In many billions of years It will become a cold empty featureless vacuum.

    Yes, but humanity likely won't be around to see it. It's a ways off.

    Yes, the sun will burn out next week, actually. Bring a coat.

    Yes, obviously the Sun will burn out too. But you have a few billion years of time before that.

    our sun has already kaboomed once, that's why we have heavy elements that are only made in nova

    That's not quite right. Our sun has never gone nova, and is a fairly young main sequence star. It's still in the first "main sequence" of fusion after accumulating from scattered matter. It's heavy enough to do fusion, but not heavy enough to really "properly" go boom at the end (or to have done so in the past).

    While novas form heavy elements, the originating star either becomes a neutron star or black hole. Sol, our sun, is a a "normal" star (though above average brightness) which means it won't properly go nova. It'll just "burn out" and become a white dwarf.

    The matter ejected by a Nova flies out into the universe and falls in the gravity wells of other Solar systems. So our heavy elements likely hail from millions of other past stars.
