A stadium-sized asteroid had a safe, well-tracked flyby of Earth on July 22, 2025.
Spanning 164.0 meters (538.1 feet), this asteroid is comparable to the footprint of a major sports stadium.
Planetary defense teams confirmed there was no danger of impact on July 22, 2025.
An asteroid this large would cause national-scale devastation if it hit, potentially triggering climate effects.
Apophis, around 370 meters across, will pass very close to Earth in 2029 but is not expected to collide.
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.
Events involving such large objects are extremely rare, and Apophis-like cases are tracked years in advance.
