Rotation of Venus?

Venus is unusual in that it rotates on its axis upside down - or spins the opposite direction than that in which it orbits the sun. If you could see the Sun from the surface of Venus, it would appear to rise in the west and set in the east. It is also unusual in that its orbital period or year (about 225 Earth days) is shorter than its rotational period (about 243 days) - but since it orbits upside-down (retrograde) an observer on Venus would experience almost two days during its year.
