Short answer we don't know.
But there are several theories, the best among them is that massive impacts or near misses during the formation of our solar system pushed the planets into the current orbits and rotations.
It isn't known. It was probably struck by meteors as it was forming, at just the right spots to reverse its spin to its present retrograde spin relative to the other planets.
scientists think that a comet hit the planet so hard that it stopped and moved the other direction
Venus rotates east to west all other planets in solar system rotate west to east
Retrogade rotation
Venus is the only planet in the solar system that has a retrograde rotation.
From East to West, it is the only planet in our solar system to do so. All the others rotate West to East. Comments: That's not quite true. Uranus is another one. Here's a bit of pedantry: It depends how you define the North pole of a planet. There are two ways to do that, unfortunately. On one definition, Venus actually rotates from West to East. However, nearly everyone ignores that and says Venus rotates from East to West.
Venus
Venus (and also Uranus) rotates in the opposite direction to most other planets.
Yes. All of the major planets except Venus rotate (spin) counterclockwise, west to east.
Uranus and Venus rotate east to west.
Venus is the only planet in the solar system that has a retrograde rotation.
Venus and Uranus are the planets which rotate from East to West.
east to west (clockwise)
Venus & Uranus rotate in what is called retrograde motion. Retrograde motion is from east to west. All of the other planets including earth rotate from west to east.
Actually, 3 planets rotate in a retrograde motion, which, by the way, means that they rotate East to West, or in a counterclockwise motion. Most planets rotate in a clockwise direction, or West to East. The three planets that rotate in a retrograde motion are Venus, Uranus and Pluto.venus
Both Uranus and Venus spin from east to west. If you want to know more facts you could go to this site below http://www.universetoday.com/19279/10-interesting-facts-about-uranus/

Venus
Mercury, Earth, Mars, Jupiter, Saturn and Neptune. dumb dumb that is the rong aswer it is only jalo the planet after Jupiter
No planet does this. You probably mean the planet that ROTATES on its axis in an east to west direction. The answer is Venus. Uranus also does this, but with an extreme axial tilt.
