From November 29 to December 13, 2021
Mercury is presently too close to the Sun and is not visible. The tiny planet passed behind the Sun (superior conjunction) on November 28; over the coming weeks, it will reappear in the evening sky where it will make a good apparition between December 29 and January 16.
Venus is the bright Evening Star that shines some 15 degrees above the south-southwest horizon, 30 minutes after sunset; Venus itself sets in the southwest two and a half hours after the Sun. In the early evening of December 6, the thin crescent moon shines 3 ½ degrees below the Evening Star.
Mars passed behind the Sun (conjunction) on October 8, and reappears gradually in the morning sky. The Red Planet can be seen 30 minutes before sunrise, low in the east-southeast. At dawn on December 2, the waning crescent Moon hangs 7 degrees to the upper right of Mars.
Jupiter appears soon after sunset 30 degrees high in the south, where it shines brightly. The Giant Planet vanishes below the west-southwest horizon around 9:30 p.m. The waxing crescent Moon appears near Jupiter on the evenings of December 8 and 9.
Saturn appears at dusk 25 degrees high in the south-southwest, 16 degrees to the right of very bright Jupiter. The Ringed Planet sets around 8 p.m. in the west-southwest. The waxing crescent Moon appears near Saturn on the evenings of December 7 and 8.
