Meanwhile, there is this one:Īn asteroid lingers near Earth and devours time (13:23 min) Or, at any rate, it devours our perception of time, as one man discovers in “Flyby.” As the asteroid Chrono-7 hazes Earth, a man wakes up in the morning to find that he is living in his future, one he had never imagined. Maybe the possibility of an asteroid hit will generate more post-asteroid apocalypse sci-fi. An asteroid hit is believed to have wiped out the dinosaurs and many other types of life forms 66 million years ago. NASA has catalogued 26,000 near-Earth asteroids so far. Meghan Bartels, “ Scientists fine-tune odds of asteroid Bennu hitting Earth through 2300 with NASA probe’s help” at (August 11, 2021)Ī paper discussing the Osiris Rex’s findings is open access. How precisely that dance plays out will shape Bennu’s trajectory over the next decades and centuries. 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. However, despite the scientists’ best efforts, predicting Bennu’s course after 2135 is still tricky. That uncertainty remains even in the new and improved models of Bennu’s future path, but with the OSIRIS-REx observations, scientists were able to dramatically reduce their uncertainty about Bennu’s fate… Scientists fine-tune odds of asteroid Bennu hitting. Scientists’ models of asteroid trajectories always include some degree of uncertainty, since a multitude of forces tug at a space rock as it rattles around the inner solar system. Scientists fine-tune odds of asteroid Bennu hitting Earth through 2300.

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. 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. The stony monster is two-thirds of a mile (1.1 kilometers) across and has a chance of impacting Earth several centuries from now on March 16, 2880, to be exact. 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%. One of the asteroids, called 2022 AP7, is 1.5 kilometers (0.9 miles) wide and has an orbit that could bring it within Earth’s path in the future, but it’s difficult for the scientists to know. ![]()
