Historical passage expected for April 2029 will allow direct observation of the asteroid and mobilizes space agencies for detailed studies
An astronomical approach of great scientific relevance already has a set date and, at the same time, draws the attention of specialists around the world.
The asteroid 99942 Apophis, known as “the god of chaos”, is expected to pass extremely close to Earth on April 13, 2029, according to predictions consolidated since its discovery in 2004.
This event will be considered one of the closest encounters ever recorded between a large asteroid and the planet.

Earth may hide two giant “continents” nearly 3,000 km deep beneath Africa and the Pacific, and scientists now reveal that these buried structures are not only different from each other but may have been shaping heat flow, volcanism, and the very internal dynamics of the planet for hundreds of millions of years.

Reduced distance places the asteroid at the orbital level of satellites
Impressively, the object is expected to reach an approximate distance of 32 thousand kilometers from Earth, a value comparable to the orbit of geostationary satellites.
Moreover, this proximity makes the phenomenon even more relevant for direct observation, something rare in events of this type.
The maximum point of the approach is expected to occur at 6:45 PM (Brasilia time).
Shortly before, around 5:30 PM, the asteroid is expected to reach its peak brightness, which will facilitate visibility.
For this reason, experts indicate that the event may be observed with the naked eye in certain regions of the planet.
Regions with better visibility and observation conditions
In this context, visibility will be more favorable in areas of Europe, Africa, and Western Asia.
On the other hand, there is still no definitive confirmation about the possibility of observation in Brazil.
If possible, it is recommended to seek locations with low artificial lighting and clear skies, which significantly increases the chances of visualization.
Additionally, atmospheric conditions will also be decisive for the observation experience.
Origin of the name and risk history of Apophis
The name Apophis originates from Egyptian mythology, where it represents an entity associated with chaos and darkness.
This symbolism has contributed to the notoriety of the asteroid since its identification in 2004.
At the time, initial calculations indicated a possible impact trajectory with Earth, which generated great concern in the scientific community.
However, later, more precise analyses ruled out any risk of collision.
Still, the object remains classified as “potentially hazardous”, mainly due to its size, estimated at about 375 meters in diameter, and its orbit close to the planet.
Space missions will investigate the asteroid before and after the passage
In light of this rare approach, several space agencies plan to closely monitor the event.
The European Space Agency has scheduled the Ramses mission, with a launch planned for 2028.
The objective will be to monitor the asteroid before, during, and after its passage by Earth.
Additionally, NASA is preparing the Osiris-Apex mission, which is expected to enter orbit around Apophis in June 2029.
This stage will occur about two months after the approach.
In this way, scientists will be able to analyze possible structural changes caused by gravitational interaction with the planet.
Scientific importance of the encounter with Apophis
This event represents a unique opportunity to deepen knowledge about near-Earth asteroids.
The proximity will allow detailed observations that would normally not be possible at greater distances.
Moreover, the data obtained could contribute to future strategies for monitoring and planetary defense.
Since its discovery in 2004, Apophis has remained under constant observation, reinforcing the importance of continuous monitoring of these celestial bodies.
In light of this historical approach and the scientific possibilities involved, an inevitable reflection arises: what can the passage of Apophis still reveal about the risks and behaviors of near-Earth asteroids?
