The “Christmas Star” of 2020

This December, Jupiter and Saturn will put on a show for skygazers that hasn’t been seen in roughly 800 years. Astronomers are calling it the Great Conjunction of 2020. On December 21 — coincidentally the winter solstice — the two largest planets in our solar system will appear to almost merge in Earth’s night sky.

Jupiter and Saturn will align so closely in the night sky that they’ll almost appear to collide from our vantage point here on Earth, creating a radiant point of light often referred to as the “Star of Bethlehem” or the “Christmas Star.”

To catch a glimpse of the phenomenon for yourself, make sure you have a clear view to the southwest about 45 minutes after sunset. The planets will be at their closest on Dec. 21, but the “Christmas Star” will be visible from anywhere on Earth for about one hour after sunset in the northern hemisphere for the entire fourth week of December.

If you’re viewing with a telescope, you may also be able to see Jupiter and Saturn’s largest moons orbiting them that week.

The next Great Conjunction this close won’t happen until March 15, 2080, so be sure to take a peek out your window for a brilliant Christmas treat.
