What Would Happen to our Earth if the Sun Disappeared?

1826
An enormous magnetic loop filled with glowing-hot gas lifted off the Sun today. Astronomers call such events "prominences" -- they're caused by explosive instabilities within the Sun's tangled magnetic field. This one stretches about 50 Earth-diameters from one end to the other. An ultraviolet telescope onboard the Solar and Heliospheric Observatory captured this spectacular view of the prominence at 13:19 UT on June 9th.

The Sun is Earth’s source of heat, light and ultimately life. Without the Sun, our planet would definitely not be how we see it now. Listed below is a scientific timeline of what may happen if we lost our local star.

Immediately

If the Sun were to completely disappear, Earth would not know about it for eight whole minutes. It takes the Sun’s light approximately eight minutes to travel the 92.96 million miles to Earth.

Without the Sun’s gravitational influence, the Earth would continue in one direction forever, at 67,062 Miles per Hour.

After a Few Weeks

Photosynthesis would stop immediately, plants would die over the next few days and weeks, while larger trees would survive for years. There is enough Oxygen on the planet that humans and animals would still be able to breathe for thousands of years, after the smaller plants disappear.

After the First Year

The average temperature on Earth would be – 100 degrees fahrenheit.

After Two to Three Years

After Twenty to Thirty Years

The temperature would drop to the point that the atmosphere would begin to become liquid. The air would become clouds, then rain, then snow. It would be a slim chance that humans are still alive, but, with enough planning.

After a Billion Years

The Earth would have traveled over 100,000 light years.

If the Earth is captured by the orbit of an alien star, it could have the potential to relive its life-cycle, allowing the microscopic organisms to evolve and potentially repeat the pattern.
