A recent study confirms that the asteroid Apophis, dubbed the “God of Chaos,” will not collide with Earth during its close flyby in 2029. Despite considering previously unaccounted factors, simulations show there is almost zero risk of impact.
Apophis, measuring approximately 1,100 feet (340 meters) across, gained notoriety due to its close approach to Earth and potential hazard to cities. Named after the Egyptian serpent god of darkness, it was initially considered a potential threat when discovered two decades ago. However, subsequent observations have revealed it will safely pass Earth at a distance of about 23,200 miles (37,400 kilometers).
The new study, accepted for publication in the Planetary Science Journal, factored in the possibility of Apophis being diverted toward Earth by a collision with another asteroid. However, simulations show this scenario to be highly unlikely. Even the closest encounter Apophis will have with another asteroid, Xanthus, in 2026, poses no threat of deflection toward Earth.
Although Apophis poses no immediate danger, scientists plan to study it further. The spacecraft OSIRIS-APEX, formerly known as OSIRIS-REx, will rendezvous with Apophis in 2029 to examine how its close pass by Earth affects its shape and structure. Understanding these changes could provide insights into its future behavior.
While Apophis no longer poses a threat, astronomers remain vigilant, underscoring the importance of continued monitoring of near-Earth asteroids.
