![]() House bill would give tax credit for rare earth magnetsA Democrat in the U.S. Thanks to a visit by a NASA spacecraft, scientists have a much greater understanding of the near-Earth asteroid, its upcoming closest approaches to Earth - and whether it could impact our planet. NASA's OSIRIS-REx mission reveals key insights into hazardous asteroid Bennu's approach to Earth Bennu is one of the most hazardous known asteroids in our solar system. Odds of ever reporting news lower than previously thought From 0000000000000000000.2 to 000000000000000000000.21 Kinda feel like a mass extinction event would be right on brand about now.'it's the end of the world as we know it and I feel fine'. Odds of asteroid Bennu slamming into Earth are higher than thought - but don't panic yetOdds of asteroid Bennu slamming into Earth are higher than first thought - but don't panic just yet. “We shouldn't be worried about it too much,” said Davide Farnocchia, a scientist with NASA 's Center for Near Earth Object Studies at the Jet Propulsion Laboratory in Pasadena, California, who served as the study's lead author. The bad news is that the space rock has a slightly greater chance of clobbering Earth than previously thought. ![]() Higher but still slim odds of asteroid Bennu slamming EarthThe good news is that scientists have a better handle on asteroid Bennu ’s whereabouts for the next 200 years.

(T&C's Apply) Read more > Crucially, it also grabbed a surface sample. On and beneath its pitch black surface, Bennu may contain chemicals and rocks from the birth of the solar system.Plus,(1,673 feet) from pole to pole, Bennu is suitably large for an investigatory mission.Sample From the SurfaceFor these reasons Bennu was selected as the target for OSIRIS-REx, and from late 2018 until earlier this year a probe had been circling the space rock to gather as much data as it could on its orbital path, size and shape, mass, composition and spin. That means it's both very old-scientists think it formed over 4.5 billion years ago-and rich in carbon and might contain organic compounds. For one thing, the asteroid's average orbital distance from the sun is around 105 million miles, which is relatively close to that of the Earth at 93 million miles.What's more, it is a rare type of asteroid known as a B-type. The hulking space rock has been studied extensively over the years, and scientists have calculated the risk of an impact with Earth in the far future.Īside, Bennu is of scientific importance for a number of reasons.
