Is our Sun getting hotter & expanding every day ? Will it swallow all the planets & die?

Answer 1

The Sun will use up its hydrogen fuel in a few billion years. At that point, it will shrink a bit because of the gravity of its own matter. At some point in the collapse, the helium nuclei will begin to undergo fusion creating heavier elements. This will cause the surface to expand and as heavier elements are formed, the Sun will evolve into a Red Giant. Its surface will be somewhere around the orbit of Mars--thus vaporizing Mercury, Venus and the earth along the way. The Sun is not massive enough to go supernova, only nova. It will end its life as a white dwarf.

Answer 2

The sun has sun storms where the temperature is lower than the surrounding areas, and also has bursts of activity called solar flares, but I do not believe it is getting hotter in general. At least not significantly hotter at the moment.

Someday it WILL get bigger though. This will occure towards the end of the sun's life. It will cool as it expands and turn into a red giant. It will most certainly swallow Mercury, Venus, and Earth in this process, but not the outer planets. Eventually the outer layers of the sun will be blown off in the form of a planetary nebula and the sun will become a white dwarf, having only it's hot carbon core and nothing left to "burn". This will eventually cool until the sun is just a dark cold giant diamond surrounded by nebula.

Our sun will not become a supernova/black hole, it's not massive enough.

Answer 3

Actually, the sun will get cooler, not hotter. However, it will expand and be closer to the Earth, so for us it will seem hotter. Either we could figure out a way to live on Mars and survive the lack of a magnetosphere so we don't all become sterile mutants (or find a way to generate one), or there's a relatively simple way to stay on Earth. You alter the course of a large asteroid, so that it flies by Earth every hundred years or so, close enough to gravitationally tug on the Earth. Since the Earth will be inhabitable where it is for at least another billion years, possibly another five, the progression could be slow- less than a meter every passing. The Earth would be pulled slowly into a new projected habitable zone, and not so fast that it would escape the current habitable zone and freeze over. Interesting question.

Answer 4

yes.

as a star dies, which is what all stars do from the time they are born, they expand, and use up their gas. but they also get hotter, and grow into a supernova. when this happens, every planet up till the earth will be engulfed in the sun, and the remaining planets will be bathed in radiation.

then, the sun will shrink, and get even hotter. it will become a white dwarf, and eventually implode, and become a black hole, where it will spinn in silent destruction for millenia, untill that too runs out of energy and dies.

Answer 5

Yup! You are correct! This will happen in a few billion years. Our solar system is about 4.6 billion years old and the sun has billions of years left in it before it goes through any large expansion that will harm the Earth. The sun has much more hydrogen to convert into helium, as fuel, before it expands and then dies.

Answer 6

Actually, the most recent study and research says that it is getting dimmer.
When the flights were halted do to the incidence on 9-11, it allowed the scientist to study the sun, without an interference.
And, they concluded that the sun is dimming, giving us less heat than we have ever been exposed to before.

Answer 7

Of course the sun expands...I don't think the sun will die in our time...What about the talking of the ice-age...Earth is to turn into a cold icey waste land...So,whats up with all of that???

Answer 8

If the sun does swallow the planets. It won't die, it will grow.

Answer 9

The main problem with the earth is we are depleting the ozone layers, the ozone layers are like the earths "sun blocker". when i say depleting, i mean causing holes in it by using cars, and in old times by putting spray in your head. so in this way, the sun's rays seem more potent because we are loosing our protection. a lot of scientists have speculated that in a few years the polar caps will begin to melt, and the ocean level will begin to raise and cause chaos and panic all over.... so yeah

Answer 10

It is believed that in the very distant future the sun will reach it's "red giant" phase and balloon to a size that will reach to the vicinity of the orbit of Mars.
