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.

2 days ago · I've been waiting to see the results of analyzing the samples of asteroid (101955) Bennu returned by the OSIRIS-REx mission, and they've just come out. At right is a shot of the probe collecting a sample in 2020; the capsule was returned to Earth in 2023. ... The Bennu samples are more nitrogen-rich (75x as much ammonia, for example), while the ...

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.

小行星101955（臨時名稱1999 rq 36 ） [6] 是林肯近地小行星研究小組在1999年9月11日發現的一顆阿波羅型小行星。它是歐西里斯任務（osiris-rex計畫）在2023年攜帶樣品返回地球任務鎖定的目標 [7] [8] 。

Nov 21, 2024 · Scientists first caught sight of Bennu on Sept. 11, 1999, with a one-meter telescope near Socorro, New Mexico, during the Lincoln Laboratory Near Earth Research (LINEAR) survey. The asteroid was within 0.05 astronomical units of Earth (about 20 times the distance from Earth to the Moon).

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. It is named after the Bennu, the ancient Egyptian mythological bird associated with the Sun, creation, and rebirth.

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.
