The correct option is A-4, B-3, C-2, D-1
Explanation
The orbital period (revolution time) of a planet is the duration required to complete one full orbit around the Sun. According to Kepler's Third Law of Planetary Motion, the square of the orbital period is directly proportional to the cube of the semi-major axis of its orbit. Consequently, as the distance from the Sun increases, the time taken to complete a revolution also increases.Analysis of the Matches:
- A. Earth: Being the third planet from the Sun, Earth completes one revolution in approximately 365.25 days. Thus, Earth matches with 365 days (4).
- B. Mars: As the fourth planet, Mars is more distant than Earth. It takes approximately 687 Earth days to complete one orbit. Thus, Mars matches with 687 days (3).
- C. Jupiter: The fifth planet, Jupiter, is significantly farther away. Its orbital period is approximately 11.86 Earth years. Thus, Jupiter matches with 11 years, 11 months (2).
- D. Saturn: The sixth planet, Saturn, takes approximately 29.46 Earth years to revolve around the Sun. Thus, Saturn matches with 29 years, 5 months (1).
Key Takeaway: The revolution period of planets follows the order of their distance from the Sun: Mercury (shortest, ~88 days) < Venus < Earth < Mars < Jupiter < Saturn < Uranus < Neptune (longest, ~165 years).
