Bennu Bennu is a carbonaceous asteroid in the Apollo group. Discovered by the Lincoln Near-Earth Asteroid Research (LINEAR) project in 1999, it is named after Bennu, a bird of Egyptian mythology associated with the Sun, creation, and rebirth. Bennu has a mean diameter of 490 metres (1,610 ft) and has been observed extensively by the Arecibo Observatory planetary radar, the NASA Deep Space Network, and OSIRIS-REx, a NASA mission that landed on and has returned samples of the asteroid to Earth. Bennu is classed as a potentially hazardous object, with a cumulative 1-in-1,750 chance of impacting Earth between 2178 and 2290. This mosaic image was produced in 2020 from photographs based on two years of close observation of Bennu by OSIRIS-REx. Photograph credit: NASA / Goddard Space Flight Center / University of Arizona
