How old is the sun? That was our daily question in multimedia class, and I was curious so i decided to look it up. Turns out that the sun was formed 4,500,000,000, four and a half billion years ago. When the sun is 7 billion years old, it will start to get bigger and cooler. By the time it reaches it's five billionth birthday it will have changed into a red giant and will stretch out to near where the earth is today.
