75-Centimeter Shape Model (Mar. 2019)

After studying asteroid Bennu at close range for three months, the OSIRIS-REx mission team has developed a new shape model with a 75-centimeter resolution. This more precise model, which was created using imagery taken by OSIRIS-REx’s PolyCam camera, shows features on Bennu smaller than one meter.

Preliminary Shape Model (Nov. 2018)

This preliminary shape model of asteroid Bennu was created from a compilation of images taken by OSIRIS-REx’s PolyCam camera during the spacecraft’s approach toward Bennu during the month of November, 2018. This 3D shape model shows features on Bennu as small as six meters.

Radar-Based Shape Model (2013)

The OSIRIS-REx  team planned the spacecraft’s mission using a shape model of asteroid Bennu that was developed in 2013 and based on radar observations from Arecibo Observatory and Goldstone tracking station. Although the original model did not predict the surface topography of Bennu in detail, at least one large rock formation was predicted in the southern hemisphere.
