In April 2029, the 99942 Apophis asteroid is expected to pass within approximately 32,000 kilometers of Earth. Recent reports suggest there is a possibility that the asteroid could collide with man-made space debris during this close approach.
Operative Information Center-OMM reports that international media outlets have highlighted this potential interaction.
According to a study published in "The Planetary Science Journal," researchers from the Italian National Research Council (CNR) simulated the flight trajectory of Apophis alongside the distribution of space debris located in geostationary orbit (GEO). The findings indicate that while Apophis poses no direct threat to Earth, there is a non-zero probability of a collision with accumulated space debris.
Scientists emphasize that such a collision would not alter the asteroid's orbit or create new risks for our planet. However, an impact could potentially create small craters on the asteroid's surface and generate dust clouds. This scenario presents a challenge for upcoming scientific missions, including the European Space Agency's (ESA) RAMSES and NASA's OSIRIS-APEX, which are scheduled to study the effects of Earth's gravity on the asteroid, as well as surface shifts and seismic activity during the flyby.
Experts note that an unexpected collision with space debris could complicate scientific observations of how Earth's gravity influences the asteroid. The study also highlights significant gaps in the current tracking of small debris in geostationary orbit. To address these challenges, there are plans to map high-orbit space debris more accurately by 2029, utilizing new telescopes to be deployed under the European Union's Space Surveillance System.
The Apophis asteroid, discovered in 2004, has long been a subject of intense scientific interest due to its proximity to Earth. While initial calculations once suggested a potential impact risk, subsequent observations have confirmed that it will safely pass by our planet, providing a rare opportunity for researchers to study a near-Earth object in detail.
