Venus has the longest rotation period (day) of all the major planets in the Solar System. While the Earth takes 23 hrs 56 mins 04 secs to complete one rotation, Venus takes 243.16 'Earth days' to spin once through 360 degrees. Due to its being closer to the Sun, the length of Venus' year is shorter than Earth's, lasting 224.7 days, so a day on Venus is actually longer than its year.
