Titan, Saturn’s largest moon, is magnitude 8.5 - an easy target for small scopes. A waxing crescent Moon stands 5° southeast of the planet on Dec. The rings’ apparent tilt to our line of sight drops below 14° late in December. Its disk spans 16″ and the rings stretch a majestic 36″. Saturn lies in eastern Capricornus and starts the month at magnitude 0.7, dropping to magnitude 0.8 by the 23rd. But catch it early, as the ringed planet sets by 10 P.M. Saturn is over 30° high in the south at dusk in early December. Follow the pair as their visibility increases into the third week of the month. 8, Venus is 1.5° high and Mercury is 2° higher 30 minutes after sunset, making them easier to observe in twilight. Mercury stands 3° east of Venus, shining at magnitude –0.6. Venus is relatively easy to spot at magnitude –3.9, but it’s less than 1° high 30 minutes after sunset. 1, the duo sets within 38 minutes of the Sun.

It’s also your last chance to grab a good view of Saturn before it sets early in the evening. Mercury and Venus make a fine pair after sunset, low in the southwest. It’s even occulted by a bright Full Moon for parts of the U.S. Mars grabs the most attention, reaching its most favorable Northern Hemisphere opposition in years. This month, all five naked-eye planets are visible in the evening sky soon after sunset.
