Detailed explanation-1: -Our Sun is 4, 500, 000, 000 years old. That’s a lot of zeroes. That’s four and a half billion.
Detailed explanation-2: -The Sun formed about 4.6 billion years ago in a giant, spinning cloud of gas and dust called the solar nebula. As the nebula collapsed under its own gravity, it spun faster and flattened into a disk.
Detailed explanation-3: -Our star will grow to be larger than we can imagine-so large that it will envelope the inner planets, including Earth. That’s when the sun will become a red giant, which it will remain for about a billion years.
Detailed explanation-4: -Instead, it will lose its outer layers and condense into a white dwarf star about the same size as our planet is now. It’s that cloud of dust expelled by our dying Sun as a white dwarf visible around our Sun as a white dwarf that will be our legacy-a spectacular planetary nebula.
Detailed explanation-5: -1 Answer. Earth is 4.543 billion years old. The Sun is 4.603 billion years old.
