A building-sized asteroid swept past Earth at a safe distance on June 21, 2025.
This asteroid spans about 25.0 meters (82.0 feet), roughly the size of a multi-story building.
Astronomers assured there was no threat of impact from this object during its June 21, 2025 flyby.
An asteroid this size could cause significant regional devastation if it ever impacted, flattening forests or damaging towns.
The Tunguska event in 1908, thought to involve a ~50-meter asteroid, leveled over 800 square miles of Siberian forest.
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.
Such objects are rare and carefully tracked, and no collision is predicted for this asteroid.
