The Sun is one of the more than one hundred billion stars that inhabit the Milky Way and many wonder what its age is in years, the answer is surprising. It is located in the center of our Solar System and contains 98.8% of its mass. It has a diameter approximately 109 times larger than that of the Earth, so it would be capable of holding up to a million Earth planets inside. We know that the Sun is relatively young and is part of a generation of stars called Population 1, but we still wonder what its true age is.

What is the age of the Sun?
Stars like the Sun usually last approximately nine or ten billion years, our Sun is relatively young since it is in the first half of its life. It was born about 4.6 billion years ago and still has nuclear fuel to remain as it is now for at least another 5 billion years.
Finally it will swell and become a cold red giant, leaving it to be the splendid bright yellow sun that we see every day and will shed its outer layers to become one, which will little by little enter its final phase as a dark and cold theoretical object. , which is known as a black dwarf.
In order to know this data regarding its age, the old objects that are around it are analyzed, such as the ancient rocks that travel through the Solar System, which in reality are debris or failed attempts that never managed to become satellites during the creation of the Solar System.
