It’s been a little cloudy lately and we miss it – but what if the Sun suddenly wasn’t there anymore?

What would the short-term and long-term effects be on Earth if the Sun suddenly vanished? Not a comforting thought but it could happen, writes Dave Reneke from Australasian Science Magazine.

Not a lot of good would come out of the Sun’s sudden disappearance. Firstly, if it were to vanish right now, we wouldn’t know for eight and a half minutes.

It actually takes that long for the sunlight to reach our eye we would blissfully orbit the recently vanished star unaware of our impending demise. Suddenly, as the last of the Sun’s rays fell onto Earth’s daylight side, the Sun would simply vanish.  

Eternal night would fall over the planet and Earth would spin off into space at 25 kilometres per second. Within two seconds, the full Moon reflecting the Sun’s rays on the dark side of the planet would also go dark.

Over the course of the day, all the planets in our once happy solar system would blink out as they stopped reflecting sunlight back to Earth.​

Eventually Earth would end up as a frozen chunk of rock sailing through space. Hopefully, by then, we will have found a way to leave our once prosperous world and migrate to a new home. See it does have a happy ending.
