How did scientist determine or were able to calculate the age of our Sun ??

Answer 1

By observing other stars we can determine at what age or sun is at (look HR diagram). Biased on the Luminosity and temp and age can be found. It would be like looking at other people to guess our age like looking at white hair, facial hair, wrinkles, stuff like that.

We can also date rocks not form earth but from the solar system. They can be carbon dated age and that can tell us about how old the solar system is and about how old the sun is. Rocks from earth don't work since they are always undergoing some process that 'recycles' them.

Answer 2

The age of the Sun is presumed to be the age of the Earth, as they, along with the rest of the solar system, were formed at exactly the same time. Thus radiometric dating of rocks on Earth (or, even more accurately, meteorites) gives the age of the entire solar system.

There is no way of observationally determining the Sun's age directly; the hydrogen that the sun uses for fuel is deep inside the core where the amount present cannot be observed. The best you can do is measure the Sun's luminosity, which gradually increses over a star's lifetime. The Sun's current luminosity is in rough agreement with radiometric dates, but many other factors also contribute to the current solar luminosity so it is not an accurate method.

Answer 3

The scientists calculate the age of our sun from many factors. One is the amount of hydrogen in the sun and the rate at which it burns thus being able to determine how long the reaction has been taking place. They also use data from older star systems to establish the average life cycle of a main sequence star (that is what our sun is). Certainly not from rocks on earth which formed billions of years after the birth of the sun.

Answer 4

Here is Lord Kelvin's fascinating paper on the Sun. Obviously, the more we have learned since then, the more accurate we have become. Without math and science, understanding such matters must be quite a mystery to some people.

The science that is used today to determine the age of the Sun is called "Nucleocosmochronology".

"Nucleocosmochronology, also known as cosmochronology, is a relatively new technique used to determine timescales for astrophysical objects and events. This technique employs the abundances of radioactive nuclides in a way that is very similar to the use of C14 in dating archeological samples, save that the elements measured are typically uranium and thorium. Nucleocosmochronology has already been successfully employed to determine the age of the Sun (4.57±0.02 Ga, where Ga stands for giga-year, i.e., 109 years) and of the Galactic thin disk (8.3±1.8 Ga), among others. It has also been used to estimate the age of the Milky Way itself, as exemplified by recent study of the halo star CS31082-001. Limiting factors in its precision are the quality of observations of faint stars, and perhaps more importantly, the uncertainty of the primordial abundances of r-process elements."

Also, computer modeling and our knowledge of stellar evolution help in our calculations of the Sun's age. Please be use to visit the link below related to stellar modeling. The images there make it instantly clear how this works:

"In astronomy, stellar evolution is the sequence of radical changes that a star undergoes during its lifetime (the time in which it emits light and heat). Depending on the size of the star, this period can range from hundreds of thousands to billions of years"

Answer 5

Scientist make sure the age of the sunlight via reading different stars. additionally they estimate the quantity of capacity produced via the sunlight to supply a greater precise age of the sunlight and compares the effect with different stars they studied

Answer 6

Perhaps carbon datation of hydrogen and helium samples.
Rocks on earth are not related to the sun, unless you take for granted that the earth comes from the sun. :)

Answer 7

The dating of rocks on earth and of meteorites led to the conclusion the earth was 4.57 billion years old.

Answer 8

The age of the sun is just as old as any other star in the universe give or take 24 hours of our Creator's time.
