Nuclear Weapons will not work. Armageddon was a joke movie. You would only have a more serious threat. What we need is a repulsor beam. A huge wave of anti-gravity shot at the moving body so its course is changed

Into the sun hopefully so it is destroyed. We can barely get the damn old shuttles into orbit.... fuck if they will go any further... the new ones will... maybe.... they would need to build something out in space
