- Bennu is a small, near-Earth asteroid that was the target of NASA's OSIRIS-REx mission to collect a sample and bring it to Earth1. Initial studies of the 4.5-billion-year-old asteroid sample show evidence of high-carbon content and water, which could indicate the building blocks of life on Earth2. Bennu was discovered by the NASA-funded Lincoln Near-Earth Asteroid Research team in 19993. It likely broke off from a larger carbon-rich asteroid and has drifted closer to Earth over time4. The rocks brought back by OSIRIS-REx are the largest asteroid sample ever returned to Earth5.Learn more:✕This summary was generated using AI based on multiple online sources.

It was the target of NASA's OSIRIS-REx mission to collect an asteroid sample and bring it to Earth.science.nasa.gov/solar-system/asteroids/101955-b…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.www.nasa.gov/news-release/nasas-bennu-asteroi…The NASA-funded Lincoln Near-Earth Asteroid Research team discovered Bennu in 1999. NASA’s Planetary Defense Coordination Office continues to track near-Earth objects (NEOs), especially those like Bennu that will come within about 4.6 million miles (7.5 million kilometers) of Earth’s orbit and are classified as potentially hazardous objects.www.nasa.gov/solar-system/ten-things-to-know-ab…Bennu likely was broken off from a much larger carbon-rich asteroid about 700 million to 2 billion years ago, which is relatively recent in geological time. It likely formed in the Main Asteroid Belt between Mars and Jupiter, and has drifted much closer to Earth since then.science.nasa.gov/solar-system/asteroids/101955-b…Pieces of the asteroid Bennu, brought back to Earth in September by NASA’s OSIRIS-REx spacecraft, include crumbly rocks and dust that contain water and carbon — some of the building blocks of life on Earth. NASA provided a first glimpse of the rocks, which are the largest asteroid sample ever returned to Earth, on 11 October.www.nature.com/articles/d41586-023-03178-0
