A. Saturn
B. Venus
C. Neptune
D. Mercury
🧠 Explanation:
Venus rotates clockwise, a unique trait called retrograde rotation, unlike most planets in our solar system. This slow spin, taking 243 Earth days, affects its extreme climate and atmospheric dynamics. Observed from Earth, its backward rotation intrigues astronomers, offering clues about planetary formation. Venus’ distinct rotation challenges standard models, making it a key study in planetary science. Understanding its motion enhances knowledge of solar system diversity, contributing to research on geophysical processes and the evolution of terrestrial planets in astronomical studies.
