Which planet rotates clockwise:

A. Neptune
B. Venus
C. Mercury
D. Earth

🧠 Explanation:

Venus is the only planet in our solar system that rotates clockwise, a phenomenon called retrograde rotation. Unlike Earth and most planets, Venus spins in the opposite direction, taking 243 Earth days for one rotation. This unique trait, observed from Earth, affects its atmospheric dynamics and extreme climate. Studying Venus’ rotation provides insights into planetary formation and geophysical processes, making it a key topic in astronomy. Its clockwise spin challenges typical planetary models, contributing to research on solar system evolution and comparative planetology.
