The asteroid was first spotted on February 27 by an observatory in La Palma, one of Spain’s Canary Islands. It will pass regarding 175,000 kilometers from Earth, at a speed of 28,000 km/hour.

The goal is to discover everything that can be learned regarding an asteroid in just one week, says the scientist. This will serve as a practice for how the network will “respond to such a threat” in the future, he added. According to astronomers’ calculations, the asteroid will pass Earth once more in 2026, but at a greater distance and will not pose a risk of impact for at least the next 100 years. Small asteroids pass over our heads every day, but the passage of such a large one so close to the Earth occurs only every ten years, according to Mr. Moissl.
Defense exercises planned
The International Asteroid Warning Network has therefore decided to take advantage of such a closeness, and 2023 DZ2 will be analyzed using a series of instruments such as spectrometers and radars.
Astronomers had detected an asteroid of similar size, 2023 DW, and assessed, at the beginning of March, at a one in 432 chance of a collision with Earth in 2046. But this probability has dropped, following more precise calculations and everything risk is now eliminated.
If such an object were ever to make its way towards us, Earth would not be defenseless. Last year, NASA’s DART spacecraft deliberately crashed into the asteroid Dimorphos, regarding 11 million kilometers from Earth, and managed to divert its course.
