How old is the Sun and how do we know?

The age of the Sun was determined based on the isotopic composition of meteorites, which are considered ancient fragments of the early Solar System. By studying the isotopic composition of meteorites, scientists were able to estimate the time that has passed since the formation of our Solar System☄️

There are several methods for determining the age of the Sun, but the most accurate is considered to be the method based on the isotope uranium-238. This isotope decays into thorium-232 over time, and by measuring the ratio of these isotopes in meteorites, scientists can calculate how many years have passed since uranium-238 began to decay

The results of these measurements allowed us to establish the age of the Sun at about XXX billion years.
