Bennu does not constantly emit a stream of dust - this phenomenon occurs about ten times a month. Wherein
The reasons for this behavior of the asteroid whileunknown. Scientists know several near-Earth objects, which also emit jets of dust as they approach the Sun. It is possible that particle emissions are associated with the sublimation of ice when a substance passes from a solid to a gaseous form, bypassing liquid.
Recently, NASA appealed to users of social networkswith the proposal to find and mark on a special map all the boulders on the surface of the asteroid Bennu. This will allow the crew of the OSIRIS-REx spacecraft to choose a place to land the probe.
Earlier, HITEC told in detail about the OSIRIS-REx mission to the Benn asteroid, which is the first contender for a collision with the Earth in the future.
