- Planétarium Rio Tinto Alcan
From September 9 to 23, 2019
Mercury is lost in the glare of the sun and is not visible at the moment. The tiny planet passed on the far side of the sun (superior conjunction) on September 3, and will return 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 passed behind the sun (solar conjunction) on September 2, and will reappear in the dawn sky in October.
Jupiter shines brightly in the south-southwest during the evening. The Giant Planet appears during twilight, some 20 degrees high, and then descends toward the southwest horizon where it sets around 10:00 p.m. On the evening of October 3, the crescent Moon hangs just 1 ½ degrees to the upper left of Jupiter.
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 8:00 p.m., and sets in the southwest around midnight. The first quarter Moon shines just 2 degrees to the lower left of Saturn during the evening of October 5.
