Surface thermophysical properties determination of OSIRIS-REx target asteroid (101955) Bennu
In this work, we investigate the thermophysical properties of OSIRIS-REx target asteroid (101955) Bennu (hereafter Bennu), where thermal inertia plays an important role in understanding the nature of the asteroid’s surface, and will definitely provide substantial information for the sampling return mission. Using a thermophysical model incorporating, the recently updated 3D radar-derived shape ...
متن کاملShape model and surface properties of the OSIRIS-REx target Asteroid (101955) Bennu from radar and lightcurve observations
We determine the three-dimensional shape of near-Earth Asteroid (101955) Bennu based on radar images and optical lightcurves. Bennu was observed both in 1999 at its discovery apparition, and in 2005 using the 12.6-cm radar at the Arecibo Observatory and the 3.5-cm radar at the Goldstone tracking station. Data obtained in both apparitions were used to construct a shape model of this object. Obse...
