It's difficult to know for sure but most studies lean towards statistics which hint on average there might be one planet per star - meaning there would be 200-400 billion planets in the Milky Way. The recent Kepler space mission data also indicate that there may be as many as 40 billion Earth-sized planets orbiting habitable zones of stars in the galaxy.
