Among the following which planet takes maximum time for one revolution around the Sun?

Orbital period increases with distance from the Sun by Kepler’s third law: the square of a planet’s orbital period is proportional to the cube of its orbit’s semi-major axis [2]. The order outward among the given planets is Venus, Earth, Mars, Jupiter [1]. Their sidereal periods are: Venus ≈ 224 days [2], Earth ≈ 365.25 days [2], and Mars ≈ 687 days (≈1.88 years). Jupiter lies farther from the Sun than Mars and thus has a substantially longer orbital period (about 11.86 Earth years), so it takes the maximum time to complete one revolution among the listed options. Therefore the correct choice is option 2 (Jupiter).
