With airplanes approaching the region’s major airports, they can be easily confused for celestial objects, Saturn is about 4 degrees to the upper left of Venus. The brighter stars of Scorpius are nearby: Antares, Zubenelgenubi, and Zubeneschamali. Venus is rapidly moving eastward as compared to the starry background. Here are dates when it passes other celestial objects:
September 19: Saturn and Venus
