101955 Bennu is a carbonaceous asteroid discovered by the Lincoln Near-Earth Asteroid Research project in 1999. Bennu has a roughly spheroidal shape, an effective diameter of about 484 m (1,588 ft), and a rough, boulder-strewn surface. It is a potentially hazardous object, with a cumulative 1-in-2,700 chance of impacting Earth between 2175 and 2199. It is named after the Bennu, an ancient Egyptian bird deity associated with the Sun, creation, and rebirth. This mosaic image of Bennu consists of twelve PolyCam images taken by NASA's OSIRIS-REx spacecraft from a range of 24 km (15 mi). The primary goal of the mission is to collect a sample from the asteroid's surface, which is scheduled to take place on October 20, 2020, and return the sample to Earth for analysis.Photograph credit: NASA / OSIRIS-REx
