![]() “Not only does this allow us to better understand Bennu’s future path and if it could ever be an impact threat to Earth, but it also allows us to test and improve the overall modeling techniques that we can use on all near-Earth asteroids. “The OSIRIS REx mission has provided exquisitely precise data on Bennu’s position and motion through space to a level never captured before on any asteroid,” said Lindley Johnson, NASA’s Planetary Defense Officer, during the teleconference. ![]() Its only rival in this category is asteroid 1950 DA, which is about twice Bennu’s size and has about a 0.17 chance of hitting Earth in the year 2880. Though the odds of Bennu hitting these keyholes are low, the new study still distinguishes the asteroid as one of the most dangerous objects in space. That's how well we can constrain the position of Bennu.” That's the height of a basketball player. “We measured the distance between the Earth and Bennu, which at times was as large as the distance between the Earth and the Sun, with a precision of two meters. The journal is mainly targeted at school students who have a strong appetite for mathematical ideas. computer science and other topics in our journal in the coming days. ![]() ![]() “By tracking the spacecraft over two years of proximity operations, we obtained fantastic positional constraints on the position of Bennu,” Farnocchia said.

Whereas scientists had previously identified 26 keyholes measuring over one kilometer (3,280 feet) that could send Bennu onto a collision course with Earth, the new study narrows the risk down to only two keyholes. 0 Comments This delivery will allow scientists to examine asteroid material with all the advanced equipment available in terrestrial laboratories.Scientists dont have to be able to access the sample material in order to study the two-and-a-half years of spacecraft observations.

Answering that question requires scientists to chart Bennu’s current trajectoryand everything that could affect its future pathwith unprecedented precision. Scientists finetune asteroid bennu hitting Stay in the loop. OSIRIS REx has captured a range of observations during its voyage that the team used to “model the trajectory of Bennu to a level that was never tried before for any asteroid,” Farnocchia said. The key question is whether Bennu’s actual trajectory in 2135 will pass through any of these keyholes, which range from several hundred feet to a few miles wide. ![]()
