* The Sun doesn't actually rise in the west. The Sun rises in the east and sets in the west due to the Earth's rotation.

* It depends on your definition of "planet". If you're talking about planets in our solar system, the answer is none. All planets in our solar system orbit the Sun in the same direction, so the Sun always rises in the east.

However, there are some interesting points to consider:

* Other star systems: In other star systems, it's possible that planets orbit their star in a retrograde direction (opposite to the star's rotation). On these planets, the sun would indeed rise in the west.

* Perspective: If you were standing on the North Pole, you wouldn't see the sun "rise" or "set" in the traditional sense. Instead, it would circle around you, appearing to move from east to west.

So, while the Sun never rises in the west on any planet in our solar system, there are some theoretical situations where it could happen!
