2019, December 10: A Venus-Saturn Conjunction


A Venus-Saturn conjunction from 2012.

Venus has a conjunction with Saturn on December 10, 2019. Venus is beginning an appearance in the evening sky. The brilliant planet passed Jupiter on November 24, and began to approach Saturn.   This is the second conjunction with Saturn during the Ringed Wonder’s current apparition (appearance).  Watch Venus close the gap on Saturn and pass it on December 10.

The passing of these two planets is a slow moving show that occurs over several nights.  First, find a clear horizon in the southwest, free from trees, houses, buildings, and other possible obstructions.

In the charts that follow, several of them are displayed for a time interval after sunset.  Use local sources for the time of your sunset.  

2019, December 2: Venus is about 10 degrees to the lower right of Saturn.

On December 2, 45 minutes after sunset, shows Venus about 9° up in the southwest. It is about 10° to the lower right of Saturn.  On the next evening, December 3, the three evening planets – Venus, Jupiter, and Saturn – are nearly equidistant tonight, but they are not along the same arc in the sky: Venus – Saturn, 8.6°; Venus – Jupiter, 9.7°.

2019, December 5, Venus passes the star Sigma Sagittarii. Venus is about midway between Jupiter and Saturn.

Venus continues to move eastward compared to the starry background toward Saturn.  On December 5,  Venus passes 1.9° to the upper right of Sigma Sagittarii.  Venus continues to close the gap on Saturn. Venus – Saturn separations until the conjunction: Dec 7, 4.3°, Dec 8, 3.3°; Dec 9, 2.4°.

Venus passes Saturn on December 10. At mid-twilight (about 45 minutes after sunset), Venus, over 11° up in the southwest, is 1.8° to the lower left of Saturn.

Venus continues eastward against the starry background, moving farther away from Saturn. on December 19, one hour after sunset, Venus, 12° up in the southwest, is nearly 10° to the upper left of Saturn. Venus moves into Capricornus.
