how old is the sun?

Answer 1

The Sun is about 4 1/2 billion years old. Humans have only been around for a tiny, tiny fraction of this time. As a comparison, if you think of 4.5 billion years as the length of a 12 inch ruler, then the time humans have existed wouldn't even be the width of the lines marking the inches. (Metric equivalent is 30.5cm and it would still be just the width of the markings.)
The Sun will remain more or less the way it is now for about another 5 billion years. After that, it will exhaust the hydrogen it currently "burns" and will enter a new phase of existence. During this phase the Sun will begin "burning" helium and will expand to about 100 times its current size and become what is called a red giant. Once it runs out of helium it will collapse into a much smaller object called a white dwarf

Answer 2

The Sun is younger than Earth and older than the moon.
As the Sun and the Moon where made to serve the Earth.
The Earth was there before time began, frozen with water.
Then the Sun and the Moon were created, and life began on our Solar System. Real Time.
How old is the Sun? Its Birthday was called the First Day, millenniums of years has passed since that first day.
But considering the fact that the Sun is timeless, as it is itself the source for time. Then the question should be: How old is the Moon? Well the Moon is younger than Earth and younger than the Sun but older than the clouds. So the question should be: How old are the clouds? etc. Then you shell find that time is an illusion as there is only an infinity. The Sun is old today as it was old on its First Day reflected on our Earth.

Answer 3

Well yes, but it could hardly have come into existence before the Big Bang, could it?

As the universe is estimated as being 13.7 billion years old, the Sun was not created immediately after the Big Bang but had to wait for another 9.2 billion years,

In that time a lot of other stars lived and died, stars referred to as Population III and Population II stars.

Shortly after the Big Bang, the universe was comprised entirely of hydrogen, helium, and trace amounts of deuterium and lithium. These elements were created during the era of nucleosynthesis, (which lasted from .0001 - 3s after the Big Bang.) These primitive atomic structures made up the primordial material from which the first stars were born.

The first stars, referred to as Population III, were incredibly massive and, during their lives, they created the elements up to iron in a process known as nucleosynthesis. These large stars had spectacular deaths through supernovae and created all the elements heavier than iron. This "polluted" the universe with metals and created the meateials from which Population II stars came to form.

The next generation of stars were born out of these materials left by the supernova outbursts. Thus, the most metal-poor objects were born the earliest.

As subsequent generations of stars were born, they became more metal-enriched, as the gaseous clouds from which they formed became more metal-rich. The next generation of stars are known as Population II and are the earliest stars which have been directly observed.

Population I stars are the young star population, having formed in the last few billion years, and are generally found in the disk of the Galaxy.

Generally, the youngest stars are found further in, and intermediate population I stars are further out, etc. The Sun is considered an intermediate population I star. Population I stars have regular elliptical orbits of the galactic centre. They are considered to be metal-rich because they have formed after the remnants of population II stars (metals) were present in the inter-stellar medium

It is thought there was a supernova in the vicinity nearby that provided the Sun and the planets with the heavier elements needed for life to emerge.

So there are distinct advantages in being on a planet of a Population I star, if life is to emerge there,

Answer 4

The Sun is dated at 4.5 billion years old, satisfyingly close to the 4.56 billion year age of the Solar System as found from the study of meteorites.

Answer 5

my sun is 7 years old,in second grade

Answer 6

The Sun's age is the age of the Solar System as a whole. A star's age is related to its luminosity (how quickly it is using up its energy) and its mass (how much material it contains).

Answer 7

Last time i sent it a birthday card it was 5 billion years old, old fella but still has a lot of heat left

Answer 8

More to the point how old is EARTH? Sorry i don't know how old the sun is, do you?

Answer 9

the sun can into existience after the big bang. i think it is 4.5 billion years old

Answer 10

4.5 Billion years old. About half way through it's life.
