Asteroid Apophis to Pass Closer Than Many Satellites in 2029

• April 16, 2026

Discovered more than two decades ago, asteroid 99942 Apophis has been under close observation due to its potential threat to Earth. Named after the ancient Egyptian deity associated with chaos, darkness, and fire, Apophis gained notoriety as one of the first near-Earth asteroids identified with a significant chance of impact.

Initially, its orbit suggested a possible collision with our planet on April 13, 2029, raising concerns among scientists and space agencies. Since then, continuous monitoring and refined trajectory calculations have been conducted to better understand the asteroid’s path and assess the actual risk it poses.

Record Close Approach in 2029

In 2029, Apophis will make an exceptionally close pass by Earth, coming nearer than many artificial satellites that orbit our planet. This unprecedented proximity will place the asteroid well below the altitude of several satellites, an event rarely witnessed in the history of modern astronomy. Such a close encounter offers a unique opportunity for astronomers to study an asteroid up close using ground-based and space telescopes, as well as potentially deploying observation missions.

While the close approach has sparked significant public and scientific interest, current data indicate that the asteroid will not impact Earth during this flyby. Instead, the encounter will alter Apophis’s orbit, and ongoing observations will be critical to updating projections for its future trajectory.

The 2029 event highlights the importance of tracking near-Earth objects (NEOs) capable of coming into close contact with our planet. Continuous advancements in observation technology and international collaboration remain key to detecting, monitoring, and, if necessary, mitigating potential threats posed by space objects.

As Apophis approaches, space agencies and astronomers worldwide are preparing for intensive observation campaigns to gather detailed information about its composition, structure, and orbital dynamics. The insights gained from this event are expected to enhance understanding of asteroid behavior and improve future preparedness for similar encounters.

Asteroid Apophis, once considered a major collision risk, will fly closer to Earth in 2029 than many satellites orbiting above.
