A　precise　dynamic　model　for　towing　and　removing　a　defunct　satellite　with　solar　panels　in　orbit　using　a　tethered　net　often　has　low　computational　efficiency　owing　to　the　complex　contact　and　collision　between　the　net　and　panels,which　is　not　conducive　to　research.To　solve　this　problem,a＂single　main　tether-multiple　subtether＂bifurcation　structure　with　beads　was　employed　as　the　tethered　net　model.This　study　investigated　the　dynamics　of　tethered　defunct　satellites　with　solar　panels,particularly　the　behavior　of　the　attitude　of　the　tethered　satellite,oscillation　of　the　main　tether,and　vibration　of　solar　panels　under　different　conditions.The　results　showed　that　different　attachment　configurations　of　the　subtethers　and　the　flexibility　of　the　main　tether　have　an　evident　impact　on　the　dynamic　characteristics　of　the　system.
