How can something orbit north south or south north?
I understand that pretty much everything from comets, planets and our own weather that everything tends to gravitate with an east west or west east movement. I get the idea of how an object in orbit gravitates around the planet but that is with a west east kind of movement. If an object is orbitting earth and has a north south orbit would it not need propulsion to continuosly push this object to match the speed of earth as it goes around it? If an object is propelled would it not be considered flying instead of orbitting? Wouldn't an object in a north south or south north, however you want to look at it, orbit would then be moving in more of a corckscrew path to maintain a straight line?
