The asteroid to the form of immense peanut could, according to the observatory, one day constitute a danger to the Earth. According to the scientists, it could be that one day it could one day cross the road of the Earth and cause serious damage because of its speed, 70 000 km / h and its size, 200m wide.

Scientists are therefore trying to calculate the trajectory of the asteroid and continue to monitor it. "Unlike natural disasters, an asteroid impact can be avoided," says one researcher. "That's why information gathered by Arecibo can be used by NASA to prepare a defense mission."
