Humanity may be long gone by then, or perhaps we’ll have already colonized another planet. Additional resources: Find out what will happen to the Earth when the sun dies, from Live Science.

Will the Sun burn out?

In about 5.5 billion years the Sun will run out of hydrogen and begin expanding as it burns helium. It will swap from being a yellow giant to a red giant, expanding beyond the orbit of Mars and vaporizing Earth—including the atoms that make-up you.

Did the Earth ever get a direct hit from the Sun?

In 2012 when the rumours of the apocalypse were at its peak, the sun had ejected out a huge amount of CME towards the earth’s orbit. We were lucky that our earth was not in the same part of the orbit, therefore, missed a direct hit. However, we had received a direct hit back in 1859 when solar flares set telegraph pylons on fire.

Does running in the Sun make you a faster runner?

That’s right – running in the sun may actually make you a faster runner. Research revealed in 2014 at the American College of Sports Medicine showed that cyclists actually saw an increase in speed after spending just 20 minutes exposed to UVA rays via a UVA lamp.

Why does the sun rise due east every other day?

The sun rises due east on only two days of the year, the equinoxes, near March 21 and September 22 each year. Every other day of the year it rises somewhere else. But where and why? The answers lie in the tilt of the Earth as it moves around the sun.

Why is the sun so important to US on Earth?

Nothing is more important to us on Earth than the Sun. Without the Sun’s heat and light, the Earth would be a lifeless ball of ice-coated rock. The Sun warms our seas, stirs our atmosphere, generates our weather patterns, and gives energy to the growing green plants that provide the food and oxygen for life on Earth.
