How do we know the age of the Sun?

answers:
ngc7331 say: its a guess based on centuries of observation

Jim say: We expect the Sun to be slightly older than the oldest meteors. We determine the age of these meteors using radiometric dating, such as measuring the ratio of uranium to lead.

Carbon dating is not used to determine the age of these meteors. The half life of carbon-14 is only 5730 years, much to short to measure the age of meteors.

Ronald 7 say: Radioactive Carbon Dating
Very technical stuff
-
Jeffrey K say: We can do radioactive dating of rocks in our solar system.
The ratio of hydrogen to helium in the sun.
Comparing the sun to other main sequence stars.

Donald Trump Supporter say: its sick

Morningfox say: We have a pretty good idea of how long it takes for something with the size and composition of the sun, to go from "birth" to its present appearance. Plus we know the ages (radioactive dating) of meteorites, and we know that they were formed just about the same time as the sun.

Robert say: Carbon dating
-
User say: we can estimate the age of the Sun by looking the oldest object around the sun and take it sample to analyze its age. that's the method.

WHANKING-WILLY say: Count how many birthday cards it has
