Orbital Dynamics in the Vicinity of Contact Binary Asteroid Systems,s chapter focuses on orbital dynamics in the vicinity of contact binary asteroids, which is estimated to constitute 10–20% of all small solar system bodies (including comets). This kind of bodies is also characterized by their highly bifurcated shape. In August 2014, ESA’s Rosetta arrived at its tar圆柱 发表于 2025-3-23 21:37:30
