text: well whats the answer? if you was to lie down at noon so you were facing the sun, then go out in six months timeand lie in the same place at the same time, would you still be facing the sun.?  if the earth rotates once every day and goes around the sun once every year. then surly you'd be facing away from the sun the second time you did it.    if you don't understand this simple thing then get two balls, put a mark on one(earth),so the mark is facing the other one(sun).now rotate the earth as it moves around the sun and you'll see that when you get half way around, if you have done a complete number of turns with the earth, the mark will be  facing away from the sun. days are counted as complete turns relative to the sun, so you are always facing the sun at noon. if you did the turns relative to the room you're in, you're modeling sidereal days. a sidereal day is one turn of the earth relative to the stars, 23 hours, 56 minutes, four seconds. if you go you at midnight six months apart, you will see that relative to the stars, you are facing in opposite directions.
