As of March 7, 2009 there are approximately 6.76 billion people on Earth. And over 300 planets outside our own Solar System (exoplanets) have been discovered - all within our own galaxy, the Milky Way. And we are just now scratching the surface of possible planets out there. Recently, unbelievable as it sounds, we have even confirmed the discovery of a planet in another galaxy (extragalactic planet) - the Andromeda galaxy, nearby to our own Milky Way!
