"We're tracking the asteroid itself, so the stars are moving by in the background and the asteroid is actually streaking by at about 30,000mph," he said. Il s’agit de la partie externe des corps suffisamment massifs pour s’être différenciés. The astronomers were only able to detect the asteroid for two days before technical and weather issues prevented further observations. Since its discovery, optical and radar telescopes have tracked Apophis as it continues on its orbit around the Sun, so we know its future trajectory quite well.

Aphosis, dont la taille est comparable à celle “de l’Empire State Building”, se rapproche de la Terre environ une fois par décennie, explique USA Today, et en sera “assez près à la fois en 2029 et à nouveau en 2036”. Although scientists have spotted small asteroids, on the order of 5-10 meters, flying by Earth at a similar distance, asteroids the size of Apophis are far fewer in number and so do not pass this close to Earth as often. In particular, two radio telescopes - the Goldstone Observatory in California, US and the Arecibo Observatory in Puerto Rico, US - tracked radio echoes off it in a bid to understand better what it is made of and how it is shaped.
