Asteroid 101955 Bennu, formally known as 1999 RQ36, is a rock in the Apollo Group that was first discovered by NASA's LINEAR project on September 11, 1999. It is a potentially dangerous site listed in the Centers Risk Table with the second is the highest cumulative assessment of the technical impact hazard scale in Palermo. The space rock is currently the goal of NASA's NASA-REX mission, which is intended to return samples to Earth in 2023, which will help researchers determine its possible outcome.
However, investigators are already warning the space agency that it could be detrimental if they did not take action.
TheTopMan YouTube channel revealed in May how a team of experts evaluated the chances of impact during a mini-series on possible threats to the Earth.
The video explains: "Asteroid 1

Considered to be the most dangerous asteroid in the universe

"According to a study by scientist Maria Eugenia Sansaturio, the 1999 asteroid may affect or not affect Earth."
Dr. Sansaturio warned in a report on the Solar System magazine Icarus
She told the Universe today in 2010: "The total probability of an asteroid 1999 RQ36 being impacted can be estimated as 0.00092, roughly a thousand chance, but what is most surprisingly, over half of this chance (0.00054) corresponds to 2182. "
There is a rather large orbital uncertainty t, due to the gravitational effects on the asteroid as it travels past Earth and other objects. NASA's OSIRIS-REx "title =" NASA "s OSIRIS-REx ” data-w=”590″ data-h=”350″/>
NASA's OSIRIS-REx will return in 2023.
It may also acquire a minimum the amount of influence from the Jarkowski effect, which is an unbalanced heat radiation from sunlight hitting one side of the asteroid and not the other that produces a small acceleration.
This effect has not been previously reported by NASA.
Dr. Sansaturio adds:  "The consequence of this complex dynamic is not only the likelihood of a relatively large impact, but also that a diversion or road diversion procedure can only be made before the impact in 2080 and easier before 2060.
"If this site was discovered after 2080, the deviation would requires technology that is currently unavailable.
"Therefore, this example implies monitoring an impact that, up to a date, does not cover more than 80 or 100 years, may need to span more than a century.

to divert these types of objects can be done with moderate resources from a technological and financial point of view. "
The new NASA mission will go back in four years, then scientists w have all the details needed to make a firm decision on the real threat to Bennu.
OSIRIS-REx will help refine their understanding of the orbit of Bennu, Principal Investigator Dante Laurereta of the Lunar and Planetary Laboratory at the University of Arizona discovered.
He told Space.com in 2016: "Our uncertainties will shrink, so this will allow us to recalculate the likelihood of impact.
"We don't know which direction it will go, it can be lowered because we just eliminated a bunch of possible key openings that Ben could hit.
"Or it can be raised because we have a higher concentration of openings in the left area than the total area of the uncertainty plane."
The work of OSIRIS-REx will also help researchers to understand better the Jarkowski effect
Somehow, scientists have assured that Bennu is not big enough to end life on Earth.
Such an impact is likely to devastate the local area, but will leave behind the erasure of civilization or causing mass extinction. 6 miles to cause a global catastrophe.
The asteroid thought it had destroyed the dinosaurs – or at least finished them – they were probably about 6 miles away
