(CBS 58) – The ‘Christmas Star’ or Great Conjunction of Jupiter and Saturn culminates Monday, December 21.

According to NASA, this happens when the two planets travel together across the sky.

#Wisconsin Sky #Forecast calls for increasingly clear skies tonight. But will they arrive fast enough to witness the closest conjunction on #Jupiter & #Saturn in 800 years?

If clear--bring binoculars! #GreatConjunction2020#GreatConjunction#MondayThoughtspic.twitter.com/0eTkfqGWAJ
