101955 Bennu is a C-type asteroid in the Apollo group discovered by the LINEAR Project on 11 September 1999. It is a potentially hazardous asteroid (PHA), that has an orbit semi-major axis distance of 1.1264 AU.  It is named after the Bennu, the ancient Egyptian mythological bird associated with the Sun, creation, and rebirth.
  101955 Bennu has a mean diameter of approximately 492 m and has been observed extensively with the Arecibo Observatory planetary radar and the Goldstone Deep Space Network.  Bennu is the target of the OSIRIS-REx mission, which arrived at Bennu on 3 December 2018.

OSIRIS-REx SPICE Kernel Archive Bundle

This collection contains detailed catalogs created during the Sample Site Selection Phase of the OSIRIS-REx mission. Each catalog features geospatial maps with comparative visualizations across all candidate sites. These catalogs are decisional products, and as such are historical documents. They are not final curated science products.

Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer (OSIRIS-REx): Derived Sample Site Products Bundle

The OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer) mission is designed to return a sample of material from near-Earth carbonaceous asteroid Bennu. OSIRIS-REx launched in September 2016 and will carry out Bennu orbit operations from December 2018 through around March 2021.  It will sample the asteroid in July 2020 and return the sample to Earth in September 2023. Along with returning a sample, it will map the asteroid and measure non-gravitational forces on the orbit.
