When our SUN explodes?

Question

how far (reference to Earth) should mankind go to be on a "safe distance" from the devastating explosion? Should we be on another galaxy to be safe?

Answer 1

The sun will NOT explode. It is not big enough.

The Sun will expand as a red giant when it runs out of hydrogen fuel in its core (approximately 5 billion years from now). When that happens, its surface may reach as far as our present orbit. This will not be good for anyone left on Earth (however, Earth will have become uninhabitable well before then).

Meanwhile, being in another galaxy may not help us if we do not choose carefully: In about 3 billion years (before the sun's red giant phase), our Galaxy and the Andromeda galaxy will collide.

Galactic colisions are slow processes taking millions of years; there is very little chance of stars hitting each other, but the tidal effects of one galaxy can eject stars from the other galaxy. it is, of course, way too early to tell if we are in any danger.

But this is the real reason we need to go elsewhere (if we still exist).

Answer 2

The sun will not explode in a supernova. However the difference to people on earth (although there wont be any) between a supernova and the red giant expansion would be moot. There is a good chance the initial red giant stage will destroy the earth, either directly or indirectly by causing the moon to crash into the earth. The final stages of the red giant stage will be even more explosive and there is no where in the solar system any potential humans could hide.
But as I said, the question is moot. Due to the suns brightening and the silicate-CO2 cycle, life on earth is already on the downhill slide. Sometime after 100 million years (some studies suggest up to 1 BY) life will become extinct. First on land then in the seas with nothing surviving except bacteria. Finally as the oceans evaporate, after about 1BY the last bacteria will die. Every living thing will have been dead for about 3BY by the time the sun expands.
Going to the CLOSEST star is probably impossible. The distances between stars is so great and the energy requirements for propulsion and life support are so great, that it is very likely manned interstellar travel is impossible. Going to other galaxies is a dream of maddness.

Answer 3

Just as Geoff has said, Our star the sun will not explode or go supernova because it dont have enough mass to do so,, What will happen is after it depleats its fuel it will slowly begin to swell and it will become a red giant but this will take billions of years, Once it becomes a red giant it will consume the inner planets, It may not consume the earth but it will burn it so that no life forms of any kind will survive,, The sun still has about 5 billion years of fuel to use up and once that is done it will then begin to swell and that process will take many millions of years,

Answer 4

there is one risk. Our sunlight would be a White Dwarf for an prolonged time. there's a tiny risk that a sequence of encounters ought to reason it to be captured in orbit around a crimson widespread close sufficient to entice fabric from the different celebrity and at last develop right into a sort 1a supernova. absolutely everyone right that's ignoring the reality that kind 1a supernovas get that way by potential of drawing mass from yet another celebrity. So it quite is incorrect to assert the sunlight will never explode by fact it would not have the mass. No white dwarf has the mass to blow up till it gets it from a miles spouse celebrity.

Answer 5

Actually, our sun won't truly explode, but it will slough off billions of tons of it's material. Before that happens, it'll become a Red Giant, and essentially engulf the first three planets; That won't be for another 4 or 5 billion years, and, hopefully by then, we'll have spready out into the galaxy.

Answer 6

Our Sun is NOT going to explode. It's not that type of star. It will slowly become a red giant, but that will take billions of years.

Answer 7

Sun will not explosed, it's the planets which are getting nearer to the sun thus there's a large possibility that its mercury which will explose first.

Answer 8

In your case - about 6 feet..........

Answer 9

dude are you like ten?
