Asteroid 101955 Bennu is a near-Earth asteroid that was discovered in 1999 by the LINEAR project. It is classified as a potentially hazardous object due to its close proximity to Earth and has been the subject of extensive research by NASA's OSIRIS-REx mission. The mission aims to study Bennu's composition, geology, and potential impact hazards, as well as collect a sample of the asteroid's surface material for return to Earth. Bennu is also of interest because it is a carbonaceous asteroid, which means it contains organic molecules that may provide insights into the origins of life on Earth.
