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 ]

Oct 16, 2020 · Bennu is a primordial artifact preserved in the vacuum of space, orbiting among planets and moons and asteroids and comets. Because it is so old, Bennu could be made of material containing molecules that were present when life first formed on Earth.

Jan 29, 2025 · Lee esta nota de prensa en español aquí.. 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 …

6 days ago · 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.

Jan 30, 2025 · It returned to Earth on Sept. 24, 2023, to drop off a capsule with material from asteroid Bennu. After dropping off the sample capsule through Earth's atmosphere, the spacecraft was renamed OSIRIS-APEX and sent on a new mission to explore asteroid Apophis in 2029.

Dec 20, 2024 · 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.

Jan 29, 2025 · Bennu — a rubble pile just one-third of a mile (one-half of a kilometer) across — was originally part of a much larger asteroid that got clobbered by other space rocks. The latest results suggest this parent body had an extensive underground network of lakes or even oceans, and that the water evaporated away, leaving behind the salty clues. ...

Oct 11, 2023 · Initial studies of the 4.5-billion-year-old asteroid Bennu sample collected in space and brought to Earth by NASA show evidence of high-carbon content and water, which together could indicate the building blocks of life on Earth may be found in the rock.

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

Jan 29, 2025 · Bennu’s parent asteroid likely broke apart 1 to 2 billion years ago, and some of the fragments came together to form the rubble pile we know as Bennu. These minerals are also found on icy bodies in the outer solar system. Bright deposits on the dwarf planet Ceres, the largest body in the asteroid belt, contain sodium carbonate.
