There are more trees on Earth than stars in the Milky Way. A major global estimate put the planet’s tree count at about three trillion, while NASA gives the Milky Way’s star count as roughly 100 to 40

A scientific analysis explains that Earth has significantly more trees than the Milky Way has stars, based on a 2015 study that improved tree-counting methodology. The article clarifies that both figures are estimates rather than exact tallies, highlighting the limitations of current observational technology.
Why it matters
It illustrates how scientific understanding evolves through improved data collection methods, moving from satellite-only estimates to ground-verified models.
