When did the Sun start existing?

roughly 4.6 billion years ago
Having formed roughly 4.6 billion years ago, our sun began its life roughly 40 million years before our Earth had formed. Since then, the sun has been in what is known as its main sequence, where nuclear fusion in its core causes it to emit energy and light, keeping us here on Earth nourished.

What is the timeline of the Sun?

And like all stars, it has a lifespan, characterized by a formation, main sequence, and eventual death. This lifespan began roughly 4.6 billion years ago, and will continue for about another 4.5 – 5.5 billion years, when it will deplete its supply of hydrogen, helium, and collapse into a white dwarf.

How do you calculate the age of the Sun?

Dating the Sun is an indirect process. There are several independent ways of estimating the age and they all give nearly the same answer: about 5 billion years. The age of the Sun can be estimated from the ages obtained from radioactive dating of the oldest meteorites.

How old is our Earth?

4.543 billion years
Earth/Age
Earth is estimated to be 4.54 billion years old, plus or minus about 50 million years. Scientists have scoured the Earth searching for the oldest rocks to radiometrically date. In northwestern Canada, they discovered rocks about 4.03 billion years old.

Is the Sun middle age?

How old is the Sun? Actually it’s middle-aged. It was formed about 4,600,000,000 years ago and we expect it to carry on pretty much as it is now for a few billion years yet – so no surprises in our lifetimes!

How long is the Sun going to last?

about 5 billion years
But in about 5 billion years, the sun will run out of hydrogen. Our star is currently in the most stable phase of its life cycle and has been since the birth of our solar system, about 4.5 billion years ago. Once all the hydrogen gets used up, the sun will grow out of this stable phase.

Can the sun explode at any moment?
