Will the Sun exist forever?
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.
How long will the Sun still exist?
five billion years
So our Sun is about halfway through its life. But don’t worry. It still has about 5,000,000,000—five billion—years to go. When those five billion years are up, the Sun will become a red giant.
Will the Earth ever hit the Sun?
The orbital distance of the Earth will increase to at most 150% of its current value. These effects will act to counterbalance the effect of mass loss by the Sun, and the Earth will most likely be engulfed by the Sun, in about 7.59 billion years.
Can the Sun become a black hole?
However, the Sun will never turn into a black hole, because it is said to have less mass than needed to turn into one. When the Sun is about to reach its end and run out of its fuel, it will automatically throw off outer layers turning into a glowing gas ring known as a “planetary nebula”.
Which is older sun or Earth?
One grain is more than 3 billion years older than the Sun, which, at more than 7 billion years, makes it the oldest solid material on Earth.
What will it be like in 100 years?
In 100 years, the world’s population will probably be around 10 – 12 billion people, the rainforests will be largely cleared and the world would not be or look peaceful. We would have a shortage of resources such as water, food and habitation which would lead to conflicts and wars.
What happens if a black hole comes to Earth?
Bad News for Earth What would happen, hypothetically, if a black hole appeared out of nowhere next to Earth? The edge of the Earth closest to the black hole would feel a much stronger force than the far side. As such, the doom of the entire planet would be at hand. We would be pulled apart.
Is it possible for life on Earth to survive the Sun?
It is calculated that the expanding Sun will grow large enough to encompass the orbit’s of Mercury, Venus, and maybe even Earth. Even if the Earth survives, the intense heat from the red sun will scorch our planet and make it completely impossible for life to survive.
How long will the Earth and the Sun last?
Cornell University astronomer Lisa Kaltenegger has run models showing that the Red Planet could then stay pleasant for another 5 billion years. About 7.5 billion years from now, the sun will exhaust its hydrogen fuel and switch to helium. That will cause it to balloon into an enormous red giant. Mars as well as Earth will be fried.
How old is the Sun in the Solar System?
The Sun is about 4.6 billion years old – gauged on the age of other objects in the Solar System that formed around the same time. And, based on observations of other stars, astronomers predict it will reach the end of its life in about another 10 billion years.
Is it possible for the sun to burn out?
Yes, the sun will eventually burn out. But not for a long, long time. The sun has used up about half of its hydrogen fuel in the last 4.6 billion years, since its birth. It still has enough hydrogen to last about another 5 billion years.

When does the Sun become uninhabitable for humans?
But the Earth will become uninhabitable much sooner than that. After about a billion years the sun will become hot enough to boil our oceans. The sun is currently classified as a “main sequence” star. This means that it is in the most stable part of its life, converting the hydrogen present in its core into helium.
Can a star like the Sun Live Forever?
Nothing on Earth stands a chance. It is easy to forget that stars, like our sun, do not live forever. Since the sun is not immortal, one day it will die, and when it does, trust me when I say you do not want to be around.
