Bennu bird from an Egyptian papyrus. The Benben stone, named after the mound, was a sacred stone in the temple of Ra at Heliopolis (Egyptian: Annu or Iunu). It was the location on which the first rays of the sun fell. It is thought to have been the prototype for later obelisks, and the capstones of the great pyramids were based on its design.

Asteroid 101955 Bennu is a B-type asteroid which is the target of the OSIRIS-REx mission. The mission seeks to characterize the asteroid by mapping the surface, studying the Yarkovsky effect, and retrieving a sample of the asteroid to return in 2023. The spacecraft was launched in 2016 and has been at Bennu since December 2018.
Bennu was chosen as the target of study because it is a "time capsule" from the birth of the Solar System. [25] Bennu has a very dark surface and is classified as a B-type asteroid, a sub-type of the carbonaceous C-type asteroids. Such asteroids are considered primitive, having undergone little geological change from their time of formation.
English: Near-Earth asteroid Bennu is a rubble pile of rocks and boulders left over from the formation of the solar system. On October 20, 2020, NASA’s OSIRIS-REx spacecraft briefly touched down on Bennu and collected a sample for return to Earth.
