Saturn Meets Venus
Following its solar conjunction during October the planet Saturn now moves into the pre-dawn morning skies on the western side of the Sun. As the Earth moves along its orbital path around the Sun, the Sun with its apparent motion along the ecliptic toward the east gives the appearance of moving away from Saturn. Gradually the distance between the Sun and Saturn increases resulting in Saturn rising earlier each day.
Try this: Observe Saturn at the same time each morning and you will notice that Saturn is appearing higher above the horizon at the same time.
Venus is also on the move eastward and since its orbital speed is greater than the Earth and the Sun’s apparent speed it (Venus) will catch up with the Sun in the next month or so. Along the way Venus will pass by Saturn, coming within 1-degree, on the mornings of November 26th and 27th as this animated graphic shows. The graphic is set at 1 frame per day and shows the sky at 6:40 a.m. CST.
The video below is a clip from a longer one I developed for a Planetarium performance last year. The longer video, Orbit, was part of a series of full-dome videos that were developed to be accompanied by original musical scores written by Daniel Eichenbaum, and performed live by Dark Matter under the 60-foot dome at the Arvin Gottleib Planetarium in Kansas City, MO.
