The planets are in nearly a single plane and in the same direction around the Sun because they formed from a rotating disk of gas and dust around the young Sun. This process is known as the nebular hypothesis. As the disk rotated, it flattened out into a disk, and the planets formed by accretion from the dust and gas in that disk. Because all the material in the disk was orbiting in the same direction, this set the stage for the planets to also orbit in the same direction and in the same plane.
