Today is Asteroid Day, a day to increase public awareness of the risks of asteroid impacts.

The JPL Center for NEO Studies (CNEOS) tracks Near-Earth Objects (NEOs) and provides impact probabilities in support of NASA’s Planetary Defense Coordination Office.

Various observatories around the world scan the sky for near-earth asteroids and comets.

The charts below shows the history of Near-Earth Asteroid (NEA) discoveries per year, by survey and by size.
