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] .

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.

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.

101955 Bennu is a C-type asteroid in the Apollo group discovered by the LINEAR Project on 11 September 1999. It is a potentially hazardous asteroid (PHA), that has an orbit semi-major axis distance of 1.1264 AU.

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.

NASA’S Origins, Spectral Interpretation, Resource Identification and Security-Regolith Explorer (OSIRIS-REx) spacecraft recently arrived at the near-Earth asteroid (101955) Bennu, a primitive body that represents the objects that may have brought …

Bennu is a low-albedo B-type asteroid2 that has been linked to organic-rich hydrated carbonaceous chondrites3. Such meteorites are altered by ejection from their parent body and contaminated by atmospheric entry and terrestrial microbes.

carbonaceous asteroid (101955) Bennu was returned o n September 24, 2023, by NASA’s OSIRIS-REx mission [1]. The mission brought back the largest sample of pristine primordial asteroidal material, largely free from the challenges of terrestrial contamination that are common in meteorite studies. The Bennu sample thus
