I know this is a stupid question, but which way do satellites revolve around the earth. Just want to confirm this as early one morning, about nearly sunrise, I saw what I thought was a satellite go from south to north, then about a minute later I saw what I thought was the first one travel back from north to south then disappear.? Could that have been a satellite, don't know much about them, so don't know. I am not up with all that, sorry.
