If you're ever following cosmic news, you may have heard of Bennou, the asteroid near the Earth, who has a weak (but higher than most) chance of colliding with our planet some 200 years from now. The asteroid is remarkable for many reasons, including the recent discovery that it is actually "active", which means it has ejected dust and gravel in the surrounding space as it is constantly on its way. to reduces the distance where the OSIRIS-REx probe goes around the rock. The probe arrived at Bennou at the end of last year to monitor the asteroid after the selection process identified which of the closest candidates to the Earth would be the best candidate for a research mission. of Bennu, which is closer than the average military helicopters flying off the Earth, as NASA does in the illustrative graph below. The Phase, and this is not only a record for Bennou, but it also stands as the closest spacecraft ever to roam an alien body anywhere in the Solar System. It will remain in this orbit until mid-August and will focus over the next few weeks on photographing the asteroid surface regularly to explore the above-mentioned dust and gravel dumping.
