101955 Bennu (provisional designation 1999 RQ36) 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] It has a cumulative 1-in-1,750 chance of impacting Earth between 2178 and ...

5 hours ago · NASA’s OSIRIS-REx mission delivered samples from asteroid Bennu, revealing crucial molecules linked to life, including amino acids and nucleobases found in DNA and RNA. The presence of ammonia and formaldehyde suggests conditions ripe for forming complex molecules in space. Scientists also discov

Oct 16, 2020 · 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.

Join experts on Thursday, January 30 at 3:00 p.m. ET as they dive into the recent findings from the asteroid sample NASA’s OSIRIS-REx spacecraft brought to Earth in September 2023.

5 days ago · A new analysis of samples from the asteroid Bennu, NASA’s first asteroid sample captured in space and delivered to Earth, reveals that evaporated water left a briny broth where salts and minerals allowed the elemental ingredients of life to intermingle and create more complex structures. The discovery suggests that extraterrestrial brines provided a crucial setting for the development of ...

Dec 17, 2024 · Bennu is a carbon-rich asteroid that is about one-third of a mile wide at its equator. Bennu may have broken off from a much larger carbon-rich asteroid about 700 million to 2 billion years ago. It likely formed in the main asteroid belt between Mars and Jupiter, and has drifted much closer to Earth since then. Bennu makes it closest approach to Earth every 6 years, coming within about 186,000 ...

4 days ago · Scientists studying samples that NASA collected from the asteroid Bennu found a wide assortment of organic molecules that shed light on how life arose.

Dec 20, 2024 · Introduction Bennu is a carbon-rich asteroid that is about one-third of a mile (half a kilometer) wide at its equator. An ancient relic of our solar system’s early days, asteroid Bennu has seen more than 4.5 billion years of history. Scientists think that within 10 million years of our solar system’s formation, Bennu’s present-day composition was already established.
