Are there more trees on Earth than stars in the Milky Way? (2016)
While both figures are rough, a recent estimate for number of trees on Earth exceeds the highest estimates for the number of stars in the Milky Way.
This map reveals that the global number of trees is approximately 3.04 trillion, an order of magnitude higher than the previous estimate. Inasmuch as these estimates approximate the actual (and impossible to verify) numbers of trees on Earth and stars in the Milky Way, the claim is accurate. To arrive at the 2015 estimate, scientists used 428,775 actual field measurements from selected areas and from different biomes, then created mathematical models to extrapolate to a global scale.
