In just over a century, the asteroid Bennu will pass very close to Earth. In fact, the information was reported by the US space agency. As detailed by NASA this Wednesday, August 11, the distance that will separate the asteroid from the Earth will be only half the distance between our planet and the Moon. It was an opportunity for the US agency to make new disclosures about spatial data.
The asteroid discovered 22 years ago
The asteroid was discovered 22 years ago. This asteroid, which is one of the most threatening to Earth, measures 500 meters in diameter. A few months ago, the Osiris-Rex probe reported samples collected during a contact that lasted only a few seconds. The arrival of its samples to Earth is scheduled for 2023. This mission had the merit of making it possible to accurately collect a lot of information about the asteroid Bennu.
We retain the next of this mission that in September 2135, Bennu will pass very close to Earth. NASA indicates that this passage will allow you to cross what is called a “gravitational keyhole.” “Typically the size of a crater will be 10 to 20 times the size of the object,” said Lindley Johnson of NASA’s Planetary Defense Coordination Office. “But the zone of destruction will be much larger than that, up to 100 times the size of the crater,” he continued.
