Here's a look at the planets that will be observable with the naked eye in the coming days. Follow these guidelines to find out where and when to look for them.
From September 5 to 19, 2022
Mercury is presently too close to the Sun and is not visible. The tiny planet passes through inferior conjunction (between the Earth and the Sun) on September 23 and will become visible at dawn after September 30.
Venus is the dazzling Morning Star that appears shortly before sunrise, very low in the east. It can be found about 5 degrees above the horizon at the start of civil dawn, about 30 minutes before sunrise. The gap between Venus and the Sun is decreasing daily, however, and the planet sinks lower in the glow of dawn with each passing day: It will vanish from sight before the end of September.
Mars is visible during the second half of the night and at dawn. The planet emerges above the east-northeastern horizon around 11 p.m. and culminates in the south at dawn, some 65 degrees above the horizon On the night of September 15 to 16, the waning gibbous Moon will rest between the Pleiades and Hyades star clusters, 9 degrees above Mars. The following night, September 16 to 17, the Last Quarter Moon will shine just 3 degrees to the left of the Red Planet.
Jupiter will reach opposition on September 26. The bright planet emerges above the eastern horizon around 8 p.m., culminates around 2 a.m. about 45 degrees above the southern horizon, and remains visible until the end of the night. On the night of September 10 to 11, the waning Moon will lie 5 degrees to the right of Jupiter and pass to its left on the night of September 11 to 12.
Saturn was at opposition on August 14. The Ringed Planet appears at dusk above the east-southeast horizon, culminates around 11 p.m. about 30 degrees high in the south, and vanishes under the west-southwest horizon before 4 a.m. On the night of September 7 to 8, the waxing gibbous Moon will shine a few degrees below Saturn, and pass to its left on the following night, September 8 to 9.
