Note the random distribution of impacts around the globe. But note also what the map and accompanying NASA report do not indicate: the year-on-year distribution of those impact events over that 20-year period. This omission enables them to give the following misleading subheading to their report:
It happens all the time: small asteroids impact Earth's atmosphereBy not providing a year-on-year breakdown of the impacts, and by including their rather banal headline, NASA leaves us to assume that these events were more or less evenly distributed over those 20 years - on average, 27 fireball events of note in 2013 (556 total events/20 years). But we have serious doubts about this.
We know from the American Meteor Society that there were nearly 3,500 observed events in 2013 alone - and just in the US.
