In a clear sky, brilliant Venus and Saturn appear in the southwestern sky during evening twilight as seen from the Chicago area. (Click the image to see it larger.) 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
