Un astéroïde va faire un coucou à la Terre, il sera plus proche que la Lune

On Wed, Sep 3, 2025, asteroid 2025 QD8 will pass in close proximity to Earth. The asteroid will be at a distance of 218,000 kilometers from Earth, which represents approximately 47% of the distance between the Earth and the Moon. The Virtual Telescope Project , based in Manciano, Italy, will facilitate tracking of the asteroid's trajectory.

Discovered by scientists on August 30, 2025, the asteroid's brightness slightly exceeds the thresholds of human vision, making it visible in certain images. At the time of discovery, it was more than 3 million kilometers from Earth.

The asteroid is traveling at over 45,000 kilometers per hour and measures between 17 and 38 meters in size. Calculations have determined that it will merely pass by Earth without posing any threat.

Astronomers regularly discover new asteroids. Generally, larger bodies are located farther away. The discovery of 2025 QD8 did not generate concern among scientists.

NASA has conducted extensive research on the near-Earth environment for several years. According to its calculations, it is highly unlikely that a massive asteroid will intersect Earth's path within the next century.

Despite optimistic forecasts, NASA continues to exercise caution. The agency successfully conducted the DART mission , which aimed to alter an asteroid's path by deploying an impactor. This mission demonstrated NASA's ability to modify an asteroid's trajectory.

In the event of a future threat, NASA can employ similar strategies to mitigate potential risks. Other agencies, such as the European Space Agency (ESA), are also developing missions with the objective of preventing catastrophic outcomes for humanity.
