90% of the asteroids near Earth that were 1 km across have been discovered and recorded by NASA's planetary defense team by the year 2010. Mountain-sized objects that are within 50 million km of Earth's orbit are known as "near-Earth objects," or NEOs. With an anticipated 50 more to record, NASA claims that none of the 887 that it is aware of pose a serious threat to the world.
At the moment, NASA is aiming to record some of the smaller asteroids, those 140 meters across or larger. About 8,000 of the 25,000 expected asteroids of this size have been logged thus far, leaving 17,000 unaccounted for. These middle-sized asteroids would pose a major threat to Earth if they entered its orbit, especially in light of the fact that a 19-metre asteroid explosion above the Russian city of Chelyabinsk in 2013 left 1,200 people injured.
