* Venus rotates incredibly slowly: A day on Venus (the time it takes to complete one rotation) is longer than its year (the time it takes to orbit the Sun).
* Retrograde rotation: Venus rotates on its axis in the opposite direction to most other planets, including Earth. This means the sun rises in the west and sets in the east.
Therefore, it's not possible to determine the number of sunrises per "year" on Venus as it rotates so slowly.
