Sombody please correct me as i think i am wrong here.Correctit is a momentum exchange. The amount gained by the spacecraft is lost by the planet. But it is not the planet rotation that gravity assist affects, it is the orbit around the sunThanks so much for clarifying that. I can now sleep at night knowing that The planets will never stop spinning, ( though they may someday become a fixed star in are sky some day,.. if humans still around that is.
