I just found out from friend about Venus rotation being opposite to all the other planets in the solar system.

Venus orbits the Sun at an average distance of about 106 million km, and completes an orbit every 224.7 days. Although all planetary orbits are elliptical, Venus' is the closest to circular, with an eccentricity of less than 1%. When Venus lies between the Earth and the Sun, a position known as 'inferior conjunction', it makes the closest approach to Earth of any planet, lying at a distance of about 40 million km. The planet reaches inferior conjunction every 584 days.
Venus rotates once every 243 days – by far the slowest rotation period of any of the major planets. A Venusian day thus lasts more than a Venusian year (243 versus 224.7 Earth days). At the equator, Venus' surface rotates at 6.5 km/h; on Earth, the rotation speed at the equator is about 1,600 km/h. To an observer on the surface of Venus, the Sun would appear to rise in the west and set in the east every 116.75 days (which corresponds to the period of continuous sunlight, on the Earth an average of 12 hours).
If viewed from above the Sun's north pole, all of the planets are orbiting in an anticlockwise direction; but while most planets also rotate anticlockwise, Venus rotates clockwise in "retrograde" rotation. The question of how Venus came to have a slow, retrograde rotation was a major puzzle for scientists when the planet's rotation period was first measured. When it formed from the solar nebula, Venus would have had a much faster, prograde rotation, but calculations show that over billions of years, tidal effects on its dense atmosphere could have slowed down its initial rotation to the value seen today

question can something like this happen to any other planet (mostly importantly to Earth) ?
