A building-sized asteroid will sweep past Earth at a safe distance on April 26, 2026.
This asteroid spans about 21.0 meters (68.9 feet), roughly the size of a multi-story building.
Astronomers assure no threat of impact from this object during its April 26, 2026 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.
