From August 26 to September 9, 2019
Mercury becomes lost in the glare of the rising sun during the last days of August, and vanishes from the morning sky. The tiny planet passes behind the sun (superior conjunction) on September 3, and returns to the evening sky for a poor apparition around mid-October.
Venus is lost in the glare of the sun and is not visible at the moment. The bright planet passed behind the sun (superior conjunction) on August 14, and will gradually reappear in the evening sky this fall.
Mars is too close to the sun and is not currently visible. The Red Planet passes behind the sun (solar conjunction) on September 2, and will reappear in the dawn sky in October.
Jupiter shines brightly in the south-southwest at dusk and during the evening. After twilight, the Giant Planet descends toward the southwest horizon where it sets around 11:00 p.m. The first quarter Moon shines less than 5 degrees to the right of Jupiter on the evening of September 5.
Saturn is also easy to see during the evening. The Ringed Planet appears in the south-southeast during evening twilight, culminates 22 degrees high in the south around 9:00 p.m., and sets in the southwest around 1:00 a.m. The waxing gibbous Moon shines near Saturn during the evenings of September 7 and 8.
