NASA's estimates of how many planets are in the galaxy are probably horribly low. But based on the recent discoveries by the Kepler space telescope, it's likely that many, perhaps even most, star systems have one or more planets. Since there are somewhere between 500 billion and a trillion stars in the Milky Way (and perhaps far more than that!) it's likely that there are between 1 trillion and ten trillion planets in the galaxy.
However, it is literally impossible to ever know if this estimate was even close to accurate. It's a Wild-Eyed Guess!THIS IS NOT THE WRIGHT ANSWER!!!!!!!!!!!!!!!!

There are those who believe that many other universes exist in what they currently describe as a multiverse. Only time will tell.
