Direct motion is the motion of planetary body in a direction similar to that of other bodies within its system, and is sometimes called prograde motion. Retrograde motionis motion in the opposite direction.
Venus
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).

It completes one rotation in a sidereal day.
Venus rotates "upside down" - meaning it rotates on its axis the opposite direction to its orbit around the sun. Uranus orbits somewhat on its side at an angle about 98 degrees to the ecliptic and is also considered retrograde.

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".
It's the only known planet that spins clockwise (backwards)

Venus. It spins the other way compared to the other inner planets.
It completes one rotation in a sidereal day.
