  • SANTA BARBARA, CALIFORNIA - DECEMBER 21: Jupiter (L) and Saturn appear about one-tenth of a degree apart during an astronomical event known as a Great Conjunction on December 21, 2020 in Santa Barbara, California. The planets, which remain about 450 million miles apart in space, have not appeared this close together from Earth's vantage point since 1623, and it's been nearly 800 years since the alignment occurred at night. The conjunction, which occurs on the night of the winter solstice by coincidence, has become known popularly as the "Christmas Star." The gas giants will not appear this close together again until 2080. (Photo by Rodin Eckenroth/Getty Images)

(CNN) — The two largest planets in our solar system are coming closer together than they have been since the Middle Ages, and it’s happening just in time for Christmas — hence the nickname of the “Christmas Star.”

While it’s not an actual star, the two planets will certainly make a bright splash in the night sky.

On the night of December 21, the winter solstice, Jupiter and Saturn appeared so closely aligned in our sky that they looked like a double planet. This close approach is called a conjunction. The fact that this event is happening during the winter solstice is pure coincidence, according to NASA.

“Jupiter and Saturn will likely stand out from the twilight glow starting around 5:00 or 5:15. With binoculars, a telescope, or a telephoto lens of 500 (millimeter) focal length or more, you may also be able to see the four largest moons of Jupiter,” said Walter Freeman, assistant teaching professor in the department of physics at Syracuse University’s College of Arts and Sciences in New York state.
