How long does it take for Venus to rotate on its axis?

The rotation period of Venus on its axis is indeed approximately 243 Earth days, making it the slowest rotation of any planet in our solar system. This lengthy rotation time is particularly interesting because it is longer than Venus's orbital period around the Sun, which is about 225 Earth days.

This unique characteristic leads to some fascinating celestial phenomena, such as the fact that a day on Venus (one complete rotation on its axis) is longer than a year (one complete orbit around the Sun). Additionally, Venus has a retrograde rotation, meaning it spins in the opposite direction to most planets, which results in its rising and setting motions being different from those seen on Earth. Understanding the duration of Venus's rotation helps illuminate the complexities of its atmospheric conditions and surface processes, contributing to our broader comprehension of planetary science.
