Running with a moon

"Do you see the string in his right hand?" I glanced at the moment. There was a rope of some kind leading from his wrist towards the screen. "That rope connects to the third moon. He's running with a five kilometer moon trailing eight kilometers above the surface of Mars like a balloon! With a single rope, he's kept the third moon trapped on the back of Mars! He's hidden the moon on the back of Mars all this time by running with it!"
