Sunday May 23rd, Saturn will stop its eastern motion in the sky. It will begin a retrograde loop that will last until mid-October. This reverse in motion is an effect of parallax produced when Earth’s faster passes Saturn on the “inside track.” The planet will stand still in the sky as it changes direction pre-dawn on Sunday. To see the change in motion, note Saturn’s distance from the star Theta Capricornus varies over several days.
