Appearances of the Haybusa2 and Osiris-Rex Target Asteroids Ryugu and Bennu

Authors: A. Soumbatov-Gur

Properties and features of asteroid (101955) Bennu to be reached this fall by NASA’s OSIRIS-REx probe are anticipated. As of September 2018 we reconcile distant groundwork data on the asteroid in a unified approach based on the paradigm of ejective formation of celestial bodies. Recent JAXA’s observations of diamond-shaped asteroid (162173) Ryugu are also systematically considered to give grounds to Bennu’s study as explosively casted out rock body. We as well analyze data on top-like main belt and near-Earth asteroids: (2867) Steins, (341843) 2008 EV5, (65803) Didymos, and others. Dozens Bennu’s constraints and properties redicted include diamond shapes, North-South dichotomy, strong equatorial mountain range, curved northern relief features, global fault, regular equatorial depressions, ten meters wide crater in high outhern latitudes, angular crater shapes, side difference in crater statistics, larger than expected density, recent geologic activity, lined distributions of substances and minerals, restricted positions of locally synthesized organic materials, x-ray and electromagnetic transients, etc.
