"To an observer on Venus, the sun would rise in the west and set in the east. This contradicts the nebular hypothesis, which predicts that as the nebula spiralled inwards all the resulting planets would rotate on their axes in the same direction, i.e. anti-clockwise, called prograde. --However, Venus rotates on its axis in the opposite direction, i.e. clockwise, called retrograde. Hence the anomalous sunrise and sunset.
Pictures of Venus from the Magellan spacecraft reveal what has been called a 'surprisingly young' landscape.
--Because the 800 to 900 impact craters are so few in number (relative to evolutionary theories of solar system history) and so fresh-looking, project scientists are theorizing that the entire surface of Venus must have been recycled somehow to 'wipe the slate clean'."
