Astronomers at the University of California-Berkeley and the University of Hawaii, using data from NASA's Kepler space telescope, estimate there are tens of billions of Earth-size, possibly habitable planets in our Milky Way galaxy.
Given that there just more than 7 billion of us on this planet, that means a planet for each of us with some spares for your picky neighbors. Or a vacation planet or two for you, maybe.
