Will the sun run out of fuel and implode, destroying the earth with it? If so, in how many years?

Answer 1

Yes, in about 5 billion years.

A professor revealed to his class that the sun would destroy the earth in its death throes in 5 billion years. Upon hearing this, one of the students became very agitated and said, "WHAT DID YOU SAY???"

After the professor repeated how much time was left, the student appeared relieved. "You had me worried.", he said, "For a minute I thought you said 5 million".

Answer 2

The Sun has about another 4 Billion years before it exhausts enough of it's Hydrogen that the production of Helium slows significantly. When that happens the diminished heat will no longer be able to keep the gasses of the sun at sufficient pressure to retain the size it has today. As that happens the Sun will collapse(not implode). As the density of the center of the Sun increases other Nuclear reactions will become common. Many of these reactions will be much more endothermic than the Hydrogen to Helium reaction. The material left on the surface of the Sun will become even hotter than it is today. The surface of the Sun will then grow and fill a volume that will include both Mercury and Venus. It may actually grow enough to engulf the Earth. At some point the Sun will become so unstable that it will explode. Most of the surface of the Sun will be Blown into interstellar space. When the explosion is passed there will be a sphere much smaller than the current Sun left. That object will no longer be producing the bright light we are used to seeing come from the Sun of today.

Answer 3

In about 4 billion years, the sun core will be filled with the helium left after the fusing of hydrogen; as a consequence, the core will collapse until it reaches a temperature that allows it to start fusing helium; the outer layers, which would still be almost pure hydrogen, will swell out from the increased heat, reaching and incinerating the inner planets including earth. Then, after a few million years only, the core will run out of helium, and since the sun does not have the mass that will allow the core to collapse to the point of igniting the lithium/beryllium/boron soup, the sun will "burp" out its outer layers, forming a planetary nebula, while the core will fall back and become a white dwarf.
So, technically, it will be the core collapse and outher layer expansionthat will destroy our planet, not an implosion in the way that word is usually understood..

Answer 4

Even if the sun were dense enough to collapse into a black hole, it would only be as large as the sun is now, outside its event horizon, planets would orbit normally, it would just be dark and cold. The sun dont have enough mass to collapse that far. Instead it will balloon into a red giant like Baetelguse 400 or so light years away. The drag caused by the balloning expanding atmosphere of the sun will cause the moon to slow, making it approach earth, reaching 11,000 miles from earth, the point that it hits the roche limit, causing the moon to scatter into a ring system like on saturn, but wont last long because of solar winds and gravity, as the earth too, slows, eventually falling into the sun.

Answer 5

Yes in about 4-5 billion years. It will run out of hydrogen to fuse and will start fusing the helium into carbon and oxygen when it enters its red giant stage, but no longer has the energy to fuse the carbon and oxygen, and collapses into a dense earth-size ball called a white dwarf.

If a star is a giant when it is fusing hydeogen into helium, it ends up actually fusing the carbon and oxygen into neon and neon into iron when it becomes a type 1 supernova.

If it becomes a type 2 supernova, it actually has enough energy so that the fusing of iron can finally begin. This is why we have all of the elements higher than iron. Betelgeuse will eventually become a type 2 supernova and scientists argue whether or not it is already in its carbon fusion stage. In this case, it will become a type 2 supernova in about one thousand years, and since it is the ninth brightest star to be seen, it will probably be a magnificent sight.

Answer 6

well, the sun will run out of hydrogen ( fuel) but the sun is not dence enough or big enough to implode, instead it Will spand and xpand, then it will Pulse realeasing tons of energy , after that it will Explode and become a white dwarf about the size of earth.

Answer 7

Not during our lifetime.
My earth science teacher says it will implode in five billion years.
Humans won't be around then.

Answer 8

i do think that it will run out of energy and the earth will die because it wont be getting any energy from the sun and will turn out like mars well maybe and i think it will implode at any time u don't know

Answer 9

In 5 Billion years the Sun will "'nova" for about one million years....

and then dwarf and finally go dark...

hopefully ... humans will have migrated to another planet or solar system by then...

Answer 10

Yes and it will be another couple billion years. The sun is only about half way thru its life span. Don't expect anything any time soon.
