Many amateur astronomers turn their eyes toward planets and moons. But there’s another class of objects that might be even more important to keep an eye on: asteroids1.
Thousands of asteroids venture close to Earth, and astronomers and planetary defense specialists are watching closely to make sure these Near-Earth Asteroids (NEAs) keep their distance. As of May 2021, 25,920 NEAs have been discovered. Some 888 of those asteroids are over a kilometer wide.
But asteroids might also be important to humanity’s future. Asteroids near Earth could one day become a vital source of metals and other raw materials.
As we look forward to Asteroid Day on June 30, we’re gathering up some of the most important facts and pervasive myths about these fascinating objects.
