a) The rotation period of Saturn is traditional rotation; winds move slowly in an eastward direction (right-pointing arrows), varying in strength with latitude and interspersed with slow speed (dots).
b) However, scientists have a new estimate of Saturn's rotation period. This rotation period is based on Saturn's dynamical meteorology. This states that the winds alternate between eastward and westward (left-pointing arrows) with
the planet's latitude.
Saturn takes a long time to revolve around the Sun because the further away the planet is from the Sun, the larger the orbit path. So, Saturn takes approximately 29.7 years to revolve.
