      It’s 4.568 billion years old! The reason we know that so well is from looking at meteorites and figuring out how old the oldest bits are. While the age is a really big number, the Sun is actually only middle aged, and continue basically as it is now for another 5 billion years.

      There’s a lot more information on the Solar System on wikipedia, including some nice animations and pictures of the planets.
