Overview of the Event
Asteroid 99942 Apophis, named after the Egyptian deity associated with chaos, is scheduled to make a remarkably close pass by Earth on April 13, 2029. This event will bring the asteroid within approximately 20,000 miles (32,000 kilometers) of the planet's surface, making it closer than many telecommunications satellites in geosynchronous orbit and nearly 12 times closer than the average distance to the Moon. Observers in the Eastern Hemisphere, including parts of Europe, Africa, and Asia, will be able to see Apophis with the naked eye, weather permitting.
Background & Context
Discovered in 2004 by astronomers Roy Tucker, David Tholen, and Fabrizio Bernardi at the Kitt Peak National Observatory, Apophis was initially classified as a potentially hazardous asteroid due to early projections suggesting a risk of impact in 2029, 2036, or 2068. However, extensive tracking using optical telescopes and radar has since ruled out any risk of collision for at least the next century.
Scientific Significance
The 2029 flyby presents a unique opportunity for scientists to study Apophis and gain insights into the characteristics of near-Earth asteroids. As it approaches Earth, the gravitational pull is expected to slightly alter its orbit around the Sun, potentially causing surface changes such as landslides or exposing fresher material beneath its weathered exterior. This interaction will allow researchers to observe how Earth's gravity affects the asteroid, providing valuable data on space weathering processes.
NASA has repurposed its OSIRIS-REx spacecraft, now named OSIRIS-APEX, to rendezvous with Apophis shortly after the flyby. The European Space Agency (ESA) is also preparing a mission, named Ramses, to study the asteroid during its close approach. These missions aim to enhance our understanding of Apophis's internal structure and physical properties.
Criticism & Opposition
While the scientific community is largely optimistic about the flyby, some skeptics question the emphasis placed on the asteroid's potential for surface changes. They argue that the actual impact of Earth's gravitational influence may be less significant than anticipated, and that the results could vary based on the asteroid's internal structure and composition.
Official Statements & Responses
NASA has stated, “Even though Apophis does not pose any immediate risk to Earth, an asteroid of its size passing so close to our planet is a very rare event.” The ESA echoed this sentiment, emphasizing the flyby as a major scientific opportunity rather than a cause for concern.

What's Next
As the date approaches, global observatories will prepare for extensive monitoring of Apophis's trajectory and behavior. The scientific community anticipates that the data collected during the flyby will contribute significantly to our understanding of near-Earth objects and their interactions with our planet.
