Venus and Uranus exhibit rotations that are different from the other 6 major planets, including Earth, likely for the same reason but with very different results. These are classified as 'retrograde' compared to the west-to-east, counter-clockwise rotation that all planets are assumed to have initially possessed.
Venus - likely due to some cataclysmic impact early in its history, Venus has lost its counter-clockwise rotation, and now turns very slowly clockwise. It takes 243 days to spin once, and does not generate a strong planetary magnetic field.
Uranus - the gas giant retains its original spin, which was west-to-east, but has been "knocked over" onto its side, again likely by some large impact event. Its tilt is about 98° from the perpendicular position, so that during its orbit, its poles will each point toward the Sun at some point. Because its original North Pole is now facing slightly below the orbital plane, it can be said to always rotate clockwise, or east-to-west, as seen from above.
This affects the apparent length of days for the planet, although for a gas giant this has much less relevance. When one of its poles faces the Sun, the entire opposite hemisphere receives little or no sunlight. When a side of the planet faces the Sun, there is a more equal distribution. Its year is equal to 84.3 Earth years and it spins once every 17.24 Earth hours.
RETROGRADE CLASSIFICATION
The planet that spins opposite to Earth is Venus. It has a retrograde rotation, meaning it rotates on its axis in the opposite direction to most planets in the solar system, including Earth. As a result, on Venus, the Sun rises in the west and sets in the east.
In our solar system yes in our universe no
retrograde rotation
There really isn't one. But, Uranus rotates on its side. It still rotates in the same direction, just on its side.
The general direction of rotation of everything in the solar system is anticlockwise (counterclockwise) when viewed from an imaginary distant point above the Earth's North pole.If a planet spins the other way, clockwise, we call that sort of rotation "retrograde".
Neptune

It's Venus, not Mercury. Mercury spins slowly, but not in a retrograde rotation. Venus spins the opposite way from the other planets, except for one of the outer planets (Uranus).

Venus is the inner planet that spins with a retrograde rotation, meaning it rotates on its axis in the opposite direction to its orbit around the Sun. This phenomena causes the Sun to rise in the west and set in the east on Venus.

Venus is the only planet in our solar system that spins in the opposite direction to the other planets. Its rotation is retrograde compared to its orbit around the Sun, making it unique in this aspect.
rotation (as opposed to orbiting, which describes the earth's movements around the sun)
Rotation. Rotation is the process by which the Earth spins on its axis, causing day and night as different parts of the planet are exposed to the Sun.
