Which planet in our solar system takes longer to complete one rotation than it does to orbit the Sun?
Answer
Venus
Venus rotates so slowly on its axis that a single Venusian day (243 Earth days) is longer than its year (225 Earth days). This makes Venus unique among the planets in having a day that exceeds its year.
💡 Did you know?
Venus rotates backward compared to most planets and so slowly that one Venusian day is longer than its year around the Sun.
