How large a meteor would have to be to damage Earth:

According to: Dunbar, B. (2015, March 24). Asteroid Fast Facts. NASA. https://www.nasa.gov/mission_pages/asteroids/overview/fastfacts.html. If a rocky meteoroid larger than 25 meters but smaller than one kilometer (a little more than 1/2 mile) were to hit Earth, it would likely cause local damage to the impact area. We believe anything larger than one to two kilometers (one kilometer is a little more than one-half mile) could have worldwide effects.
