How many near Earth asteroids have been discovered so far?


11,054 (subject to change). The first asteroid, Ceres, was discovered in 1801 by Giuseppe Piazzi. To date, researchers have identified over 90% of near Earth 1km or larger objects—a body with a diameter between 0.5 and 5km would cause catastrophic damage if on a collision course with Earth.
