Cape Canaveral, FLA: The good news is that scientists have a better handle on the existence of Bennu Asteroid for the next 200 years.
The bad news is that Rock Rock has a slightly larger chance to clot the earth than previously thought.
But don’t worry: Scientists report on Wednesday that his chances are still quite low so that Bennu will hit us in the next century.
We should not worry too much, said Davide Farnocchia, a scientist with the study of objects near NASA in the Jet Propulsion Laboratory in Pasadena, California, who served as the lead author of the study.
While the attack opportunities have increased from 1,700 to 1 of 1,750 for the next one or two centuries, scientists now have far better ideas about the Bennu route thanks to the NASA spacecraft Osiris-Rex, according to Farnocchia.
So I think overall, the situation has increased, he told reporters.
The spacecraft returned to Earth on a long and round loop after collecting samples from a large pile of debris and spinning from asteroids, considered one of the two most dangerous asteroids in our solar system.
The sample would be due here in 2023.
Before Osiris-Rex arrived in Bennu in 2018, the telescope provided strong insight into the asteroid, about a third of a military diameter (half kilometer).
Spacecraft collects enough data for 2 1/2 years to help scientists better predict the asteroid orbital paths well into the future.
Their findings published in the icarus journal must also help in mapping the direction of other asteroids and giving the earth a better battle opportunity if and when other dangerous spacecraft towards us.
Before Osiris-Rex arrived at the scene, scientists placed Bennu’s chances of hitting the earth until 2200 at 1 out of 2,700.
Now is 1 of 1,750 to 2300.
The most threatening single is September 24, 2182.
Bennu will have a close meeting with the earth in 2135 when passing half the distance of the month.
Gravity Earth can change its future path and put it on a collision course with the earth in the 2200s _ smaller now based on Osiris-Rex’s observation.
If Bennu does slam the earth, it will not remove life, dinosaur style, but to make the crater around 10 to 20 times the size of the asteroid, said Lindley Johnson, Planet NASA defense officer.
The collapse area will be much greater: 100 times the size of the crater.
If the size of the Bennu object crashes into the east spawl, it will deeply destroy everything and walk along the beach, he told reporters.
Scientists have approached the curve with Bennu, which was discovered in 1999.
Finding asteroids that threaten in advance increase opportunities and choices to encourage them out of our way, Johnson said.
One hundred years from now, who knows what the technology will happen, he said.
In November, NASA planned to launch a mission to knock on an off-middle asteroid by hitting it.
The experimental target will be the bigger Moonlet of Space Rock.
