How long could life on Earth Survive with no sun?
Using both the heat and the electricity obtained from below ground, life on planet Earth could be maintained under large domes for millions of years, even without the sun. Add the energy you can get from nuclear fission and fusion, and human civilisation could go on even longer.
How long will the Sun swallow the Earth?
As shown in this animation, in the case of the Solar System this will include Mercury, Venus, and even Earth, which will all be consumed by the red-giant Sun in about 5 billion years . Eventually, Sun-like stars lose their outer layers, leaving behind only a burnt-out core, a white dwarf.
When will the sun destroy the Earth?
The sun is approximately 5 billion years old and is considered to be middle aged. So in about another 5 billion years, it will start to run out of fuel, and will swell to become a red giant that will eventually engulf all the inner planets, including the earth.

How cold will it be on Earth without the Sun?
And without sunlight, the Earth would get very, very cold. Earth’s surface temperature now averages about 57 degrees Fahrenheit, but by the end of the first week without the sun, the average surface temperature would be below the freezing point .
Can life still exist on Earth, without the Sun?
The answer is No, the Earth would not remain in any recognizable form without the Sun. There would still be a husk of a dead planet with a small amount of energy coming from the residual heat of the core which might be able to sustain chemosynthetic life in small colonies.
How cold would Earth be without the Sun?
And without sunlight, the Earth would get very, very cold. Earth’s surface temperature now averages about 57 degrees Fahrenheit, but by the end of the first week without the sun, the average surface temperature would be below the freezing point.
