Correct Answer:
B. Venus
The correct answer is Venus because it takes longer to complete a single rotation on its axis than any other planet in our solar system.
- Step 1 (Rotation Speed): Venus exhibits an exceptionally slow rotation, requiring roughly 243 Earth days to spin around just once. Interestingly, its day is longer than its year, as it takes Venus only about 225 Earth days to orbit the Sun.
- Step 2 (Direction of Spin): Venus also undergoes retrograde rotation, meaning it spins in the opposite direction of Earth and most other planets, causing the Sun to rise in the west and set in the east.
- Incorrect Options:
- Mars is incorrect because its rotational period is very similar to Earth's, taking just over 24 hours to complete one full rotation.
- Jupiter is incorrect because it is actually the fastest rotating planet in our solar system, completing a full rotation on its axis in less than 10 hours.
- None of these is incorrect because Venus is the exact scientific answer.
