As a result, scientists behind new research now say theyre confident that the asteroids total impact probability through 2300 is just 1 in 1,750. Please do not discuss the concept of the autotldr bot here. Before Osiris-Rex arrived on the scene, scientists put the odds of Bennu hitting Earth through the year 2200 at 1-in-2,700.

Summary Source | FAQ | Feedback | Top keywords: asteroid #1 Bennu #2 scientist #3 impact #4 rock #5 But to accurately identify which asteroids might actually pose a risk, scientists need to be able to calculate as accurately as possible where a space rock's trajectory will take it. Bennu is on the list of potentially hazardous asteroids (PHA). One aspect of that work is finding as many near-Earth asteroids as possible - scientists have cataloged more than 26,000 to date, according to NASA. Recently, NASA test-fired the thrusters on the OSIRIS-REx spacecraft to fine tune a. Before Osiris-Rex arrived on the scene, scientists put the odds of Bennu hitting Earth through the year 2200 at 1-in-2,700. Bennu will have a close encounter with Earth in 2135 when it passes within half the distance of the moon. for spurious transient events such as cosmic ray hits and satellite trails. Now it’s 1-in-1,750 through the year 2300. Not only are candidates assigned a well-calibrated probability of being real. In September of that year, Bennu will swing past Earth - not close enough that there's any risk of an impact, but certainly close enough that Earth's gravity could nudge the asteroid a bit on its path. Before Osiris-Rex arrived on the scene, scientists put the odds of Bennu hitting Earth through the year 2200 at 1-in-2,700. One factor that scientists were particularly concerned about is called the Yarkovsky effect, which is triggered by the constant temperature fluctuations that occur as regions of the asteroid pass in and out of daylight, gently pushing the asteroid. ![]() In addition to factors like these that affect all solar system objects, the team was also able to check the impact of two unusual characteristics of Bennu specifically: the plumes of dust that regularly shoot off the asteroid and the rock's interaction with the spacecraft itself. If the possibility of an asteroid called Bennu slamming into Earth a lifetime from now was keeping you up at night, NASA scientists think you can rest a little easier.Īs a result, scientists behind new research now say they're confident that the asteroid's total impact probability through 2300 is just 1 in 1,750.
