On April 13, 2029, asteroid Apophis will pass closer to Earth than most satellites, traveling within 32,000 kilometers of the planet. The asteroid, named after the Egyptian god of chaos, measures 340 meters and has drawn significant attention since its discovery in 2004.
Early calculations suggested a 2.7% chance of collision during its 2029 flyby, prompting international concern. Apophis earned the highest rating ever recorded on the Torino scale, which assesses the risk posed by near-Earth objects. However, subsequent studies have ruled out any impact for at least a century.
Despite the reduced threat, scientists are eager to study Apophis during its approach. The asteroid is expected to undergo surface changes due to Earth’s gravity, including tremors and possible landslides. These changes will offer researchers a rare opportunity to observe how such forces affect asteroids.
NASA’s OSIRIS-APEX mission will lead efforts to study the asteroid. The spacecraft will analyze the effects of Earth’s gravity and collect surface material for further research. Other international projects, such as Germany’s “NEAlight,” are also preparing to exploit this once-in-a-millennium event for scientific discoveries.
The close encounter will not only provide valuable scientific insights but also offer a spectacle for the public. Apophis will be visible to the naked eye, and viewing events are already being planned.
This event underscores the importance of ongoing asteroid monitoring and research, both to advance science and to prepare for future potential threats.
