Question

Why does venus rotate in a different way than other planets do?

Answer 1

The planets are conserving that initial angular momentum. Now Uranus and Venus show opposite rotation. This is due to the impacts in the early years of their formation by asteroids and planetesimals. These impacts have probably reversed their rotational direction.
