'As 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,' reports. Summary Source | FAQ | Feedback | Top keywords: asteroid #1 Bennu #2 scientist #3 impact #4 rock #5 NASA's OSIRIS-REx spacecraft has been orbiting an asteroid called Bennu for more than two years to fine-tune the agency's existing models of its trajectory. 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. An asteroid known as Bennu will pass within half the distance of the Earth to the moon in the year 2135 but the probability of an impact with our planet in the. 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. 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. 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. Scientists fine-tune odds of asteroid Bennu hitting Earth By 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. 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. This is the best tl dr I could make, original reduced by 81%. ![]()
