Moon Phases, Planets, and More!

astronomical events december 2020 - 1

December 13, 14 - Geminids Meteor Shower

The Geminids Meteor Shower is the king of the meteor showers. Many astronomers look forward to this shower every year! At its peak, the Geminids Meteor Shower produces up to 120 multicolored meteors per hour! The Geminids runs annually from December 7 to 17 and peaks on the night of the 13th into the morning of the 14th. This year the show could even last into the morning of the 15th thanks to the New Moon, ensuring dark skies. Find a dark location if possible, and get ready to see a spectacular show after midnight.

December 14 - New Moon

This is the best time of the month to observe faint objects such as galaxies and star clusters! Plan ahead for optimal imaging or observing.

December 14 - Total Solar Eclipse

A total solar eclipse happens when the Moon completely blocks the Sun and reveals the Sun’s outer atmosphere, known as the corona. This year the total solar eclipse will be visible in parts of southern Chile and southern Argentina. A partial eclipse will be visible in most parts of southern South America, the southeastern Pacific Ocean, and the southern Atlantic Ocean.

December 21 - December Solstice

The Northern Hemisphere welcomes the winter season and the Southern Hemisphere welcomes the first day of summer! 

December 21 - Rare Conjunction of Jupiter and Saturn

This rare conjunction of Jupiter and Saturn is known as a great conjunction. The last great conjunction occurred in 2000. The two bright planets will be so close that they will appear to make a bright double planet! Look to the west just after sunset for this rare planetary pair.

December 21, 22 - Ursids Meteor Shower

The Ursids is a minor meteor shower producing about 5-10 meteors per hour. The shower runs annually from December 17-25 and peaks this year on the the night of the 21st and morning of the 22nd. The best viewing will be just after midnight from a dark location far away from city lights. 

December 30 - Full Moon

This Moon was known by some early Native American tribes as the Cold Moon because this is the time of year when the cold winter air settles in and the nights become long and dark. This moon has also been known as the Long Nights Moon and the Moon Before Yule.
