Why Do Planets Orbit in the Same Direction
When the cloud finally collapses, it forms a star and shortly after planets. However, angular momentum is always conserved. That’s why planets all follow the same orbit, and why almost all of them rotate in the same direction.

Do planets have to orbit in the same direction?

Planets form from material in this disk, through accretion of smaller particles. … The planets all revolve around the sun in the same direction and in virtually the same plane. In addition, they all rotate in the same general direction, with the exceptions of Venus and Uranus.

Why do all the planets orbit the Sun in the same direction and in nearly the same plane?

It’s thought to have arisen from an amorphous cloud of gas and dust in space. The original cloud was spinning, and this spin caused it to flatten out into a disk shape. The sun and planets are believed to have formed out of this disk, which is why, today, the planets still orbit in a single plane around our sun.
