Abstract:
Studying of binary asteroids because of achieving data of existence sources in the world persuades to investigate about tethered satellite formation around binary asteroids in future missions. About 20 percent of asteroids around the sun are binary asteroids. It is going to analyse dynamics of tethered satellite around Didymos binary asteroid. Light mass of the asteroid is good reason to consider gravitational harmonic perturbation, and leads to attention about solar radiation pressure depends on distance in modelling of the dynamical system. It will be zonal harmonics up to second order and sectoral. Satellites are such a particle as an assumption; that is why attitude motion of satellites ignored. Tether is massless and rigid. Periodic orbits and stability analysis is going to be considered. It is going to approximate halo orbit. The attitude of the tether in which plane in the halo orbit dynamical surrounding must be innovative matter in this research. The tether should be supposed to be in deployed manner and deployment and retrieval phases
