On April 13, 2029, the 370-meter asteroid Apophis will pass just 31,600 kilometers above Earth's surface — closer than geosynchronous communications satellites and visible to the naked eye across Europe, Africa, and western Asia. Once feared as a potential impactor with a 2.7% strike probability, Apophis is now confirmed safe for at least 100 years, but the encounter has become a stress test for planetary defense infrastructure, international coordination, and the economics of protecting civilization from low-probability, high-consequence threats.
