Detailed explanation-1: -Answer: The sun was born about 4.6 billion years ago. Explanation: Many scientists think the sun and the rest of the solar system formed from a giant, rotating cloud of gas and dust known as the solar nebula.
Detailed explanation-2: -Therefore, the age of the sun is 4.5 billion years old.
Detailed explanation-3: -Or not so much? Our Sun is 4, 500, 000, 000 years old. That’s a lot of zeroes. That’s four and a half billion.
Detailed explanation-4: -When it starts to die, the Sun will expand into a red giant star, becoming so large that it will engulf Mercury and Venus, and possibly Earth as well. Scientists predict the Sun is a little less than halfway through its lifetime and will last another 5 billion years or so before it becomes a white dwarf.
Detailed explanation-5: -The age of the Sun can be estimated from the ages obtained from radioactive dating of the oldest meteorites. This may seem odd at first, but in fact it is extremely likely that the solar system (i.e. th Sun, planets, asteroids etc.) formed as one unit.
