As far as we know, there aren't any planets out there that don't rotate at all. The processes that form planets and other celestial bodies naturally result in rotation, meaning that all worlds spin from the outset. Our neighboring planet Venus is an oddball in many ways. For starters, it spins in the opposite direction from most other planets, including Earth, so that on Venus the sun rises in the west.
A planet does not rotating at all may not even exist, as it'll be sucked right into its host star. However, there are planets who rotates in the opposite direction as we may believe. We have our neighbor planet, the second brightest object (one being the moon itself) in the night sky, Venus, rotating anti-clockwise.
This anti-clockwise rotation of any planet is known as Retrograde Rotation.
A long-held theory is that Venus once rotated as the other planets do, but was struck billions of years ago by a planet-size object. The impact and its aftermath caused the rotation to change directions or flipped the planetary axis. Our neighboring planet Venus is an oddball in many ways. For starters, it spins in the opposite direction from most other planets, including Earth, so that on Venus the sun rises in the west. Jupiter is the fastest spinning planet in our Solar System rotating on average once in just less than 10 hours. That is very fast especially considering how large Jupiter is. This means that Jupiter has the shortest days of all the planets in the Solar System. However, because its spin and orbital directions are opposite, Venus would be quasi-non-spinning with respect to the “fixed stars” or the cosmic background radiation. From the surface of a non-spinning planet, its sun would appear to move across the sky, but the other stars would be stationary. As far as we know, there aren't any planets out there that don't rotate at all. The processes that form planets and other celestial bodies naturally result in rotation, meaning that all worlds spin from the outset.
