Historically, scientists believed that it takes Saturn 10.656 hours to rotate on its axis or about 10 hours and 39 minutes. More recently, astronomers received satellite messages indicating that the length of Saturn’s day is closer to 10 hours and 45 minutes.
Scientists do not believe that the planet has actually slowed its rotation. Instead, they think that Saturn’s magnetic field and its location have more to do with the conflicting readings. Nevertheless, Saturn’s day is less than half that of Earth’s 23.934 hour-long day. By contrast, a year on Saturn, the second largest planet in the solar system, is slightly less than 30 years on Earth.
