Why Mars appears to be moving backward
Our solar system is in constant motion, with all eight planets — and dwarf planet Pluto — orbiting the sun. Most of those planets are visible from Earth, even to the naked eye. If you track them in the sky night after night, you'll notice that their position changes slightly; as they orbit the sun, they appear to move from west to east against a fixed backdrop of distant stars.
