1 天前 · Near-Earth asteroid Bennu has a slim chance of colliding with Earth in 2182. If it does, the impact could trigger a global winter that affects our planet for years.

101955 Bennu (provisional designation 1999 RQ 36) is a carbonaceous asteroid in the Apollo group discovered by the LINEAR Project on 11 September 1999. It is a potentially hazardous object that is listed on the Sentry Risk Table and has the third highest cumulative rating on the Palermo Technical Impact Hazard Scale . [ 9 ]

2020年10月16日 · Bennu is a carbonaceous asteroid that hasn’t undergone drastic, composition-altering change, meaning that on and below its deeper-than-pitch-black surface are chemicals and rocks from the birth of the solar system.

1 天前 · The findings were modeled on near-Earth asteroid Bennu, considered by NASA to pose the highest risk to our planet in terms of proximity and impact. The asteroid measures 0.31 miles (0.5 kilometers ...

2025年1月29日 · Studies of rock and dust from asteroid Bennu delivered to Earth by NASA’s OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification and Security–Regolith Explorer) spacecraft have revealed molecules that, on our planet, are key to life, as well as a history of saltwater that could have served as the “broth” for these ...

2025年1月29日 · Nearly 60 years later, NASA’s OSIRIS-REx mission returned from space with a sample of an asteroid named Bennu, similar to the one that rained rocks over Revelstoke. Our research team has published a chemical analysis of those samples, providing insight into how some of the ingredients for life may have first arrived on Earth.

2025年1月29日 · The chemical building blocks of life have been found in the grainy dust of an asteroid called Bennu, an analysis reveals.

3 天之前 · Bennu is a relatively small asteroid that passes close to Earth about every six years. Bennu was the target of NASA’s OSIRIS-REx, the first U.S. mission to collect a sample from an asteroid and deliver it to Earth on Sept. 24, 2023.
