Asteroids like 1950 DA, over 1 km in size, are rare but closely monitored centuries ahead of possible risks.
Apophis will pass extremely close in 2029.
Near-Earth asteroids are remnants from the solar system's formation, and NASA tracks over 35,000 of them.
Space agencies around the world prioritize discovering and tracking objects of this size.
