How long is a year on saturn in earth days

Set your timers for 10 hours, 33 minutes and 38 seconds — scientists have finally figured out how long a day lasts on Saturn, cracking a lingering mystery about the ringed gas giant.

That's according to newly published research that uses data gathered by NASA's Cassini mission before the spacecraft's destruction in September 2017.

The new calculation shaves several minutes off previous estimates for a Saturn day, which scientists have been making for decades based on data from the Cassini mission and its predecessor, Voyager.

"The researchers used waves in the rings to peer into Saturn's interior, and out popped this long-sought, fundamental characteristic of the planet.
