Scientists have finally determined how many Saturn's days are – BGR



Determining the length of a day on the planet is usually quite easy. You just choose a landmark and wait to reach the same point twice in your rotation and you have your answer. For astronomers studying Saturn, this is not so easy.

Saturn has no visible landmarks to follow, and Gazi's atmosphere does not offer many hints about how fast it rotates. In addition, the magnetic field hides the speed at which the body rotates. Researchers were not sure how to track the rotation of the planet, but with the help of NASA's Cassany spacecraft data, the code was finally broken. in fact, holding the Saturn speed dial. Mankovich looked closely into the subtle wave patterns in the rings, finding that the waves were caused by specific locations on the planet while spinning, and that their tracking could solve the error of rotation once and for all. can not help sensing these oscillations in the gravitational field, "Mankovich said in a statement. "At certain points in the rings, these oscillations capture the ring particles at the right time in their orbits to increase energy gradually, and that energy is transmitted as an observed wave." that one day Saturn lasts 1

0 hours, 33 minutes and 38 seconds. Decades ago, astronomers using data from Voyager's magnetic field valued Saturn's day at 10 hours, 39 minutes and 23 seconds. This new study helps clarify these early estimates quite a bit and offers the most accurate measurements from one day on the annular planet.
