Day length in our solar system

Venus is the only planet in the solar system that rotates clockwise. All the other planets rotate

anticlockwise. Venus (radius 3,760.4 miles) is similar to Earth (radius 3,963.19 miles) in size and


structure but spins very slowly. A day on Venus is 243 Earth days long.


 Earth is the densest planet in the solar system and the only one not named after a god. Earth


orbits the sun at an average speed of 66,629 mph (107 229 km/h). One year on earth is 365.24


 days long. One day is23 hours, 56minutes and 4,06 seconds long. The extra day in a leap year


 was introduced to compensate forthe discrepancy in the Georgian calendar.
