In most cases they just appear to cross the sky in one direction. But the outer planets can sometime appear to go forward, then backward, then forward again over a period of time. To visualizer this affect, look away from where you are standing and imagine you are the earth and you are looking at a planet out in front of you. Because it is an outer planet, it takes longer to go around the sun and not all the planets have the same orbital speed. Now, as you pass the outer planet it will appear to rise and move across your line of site. As you pull away and the outer planet is located on the other side of the sun, it will appear to move across your field of vision in the opposite direction. When it comes back around, it will slowly start to move forward again. There are days when I have a lot time on my hands.
