How do scientists determine the age of our sun?

Answer 1

Assuming the Sun to be typical of the matter in the universe as a whole, spectrometer evidence indicates the relative amounts of various isotopes of hydrogen & helium as a first approximation.

Knowing the rate of hydrogen fusion, and the relative abundances of these isotopes in the universe as a whole, calculating backwards gives the time when these reactions began. It is at the point where hydrogen fusion began that the sun became a star, and hence, that is its age.

Either that, or else they countef the rings-----one for every year, you know what I mean?

Answer 2

Scientist determine the age of the sun by studying other stars. They also estimate the amount of energy produced by the sun to give a more accurate age of the sun and compares the result with other stars they studied

Answer 3

The age of the solar is presumed to be the age of the Earth, as they, alongside with something of the photograph voltaic gadget, have been formed at precisely the comparable time. subsequently radiometric relationship of rocks in the international (or, much greater accurately, meteorites) supplies the age of the completed photograph voltaic gadget. there is not any way of observationally figuring out the solar's age rapidly; the hydrogen that the solar makes use of for gasoline is deep interior the middle the place the quantity latest won't be able to be stated. the terrific you're able to do is degree the solar's luminosity, which progressively increses over a celebrity's lifetime. The solar's present day luminosity is in tough settlement with radiometric dates, yet many different components additionally make contributions to the present day photograph voltaic luminosity so it is no longer a correct approach.

Answer 4

they determine it by radioactivity. like this article: In his latest work, Dauphas has honed the accuracy of the cosmic clock by comparing the decay of two long-lived radioactive elements, uranium-238 and thorium-232. According to Dauphas' new method, the age of the Milky Way is approximately 14.5 billion years, plus or minus more than 2 billion years.
Other method is to determine how much emmissions the sun emits, cosmic rays and radiation per second

Answer 5

Per wikipedia, the sun's age is determined using computer models of stellar evolution and nucleocosmochronology. It is thought to be about 4.57 billion years old.

Answer 6

From studies, they can estimate the age of the sun by taking into account its mass and luminosity.
