There is no threat posed by this massive asteroid during its September 28, 2025 flyby.
An impactor of this scale could trigger continental devastation and secondary global climate effects.
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.
