Florence, December 21, 2020 – It is a unique and very particular phenomenon that is observed in the celestial vault. It’s the christmas star, which will be visible at sunset Monday, December 21 looking southwest. Jupiter and Saturn, the largest planets in the solar system, in their continuous movement will come to align to form in practice, for the human eye, a planet, a single luminous group. Of two planets that in themselves are particularly bright.
Jupiter and Saturn come together, and it’s a normal phenomenon, but it never happened that they were so close. Usually it is the moon, which has a much faster orbit, that joins. In this case, they are instead two planets. “Such a close conjunction between the two planets is probably the origin of the tradition of posing a star over the cabin from the cradle – they say from Planetarium of the Casentinesi Forest Park – Recent studies have given the origin of this tradition of the star in the cradle not to the passage of the comet but to the close conjunction between two planets ”.
As explained on the planetarium’s Facebook page, the approach of the two planets began on October 2 and gradually increased. Until the peak of this winter solstice. A very special phenomenon. The Google search engine has also created a Doodle to celebrate this event.
There are many amateur Tuscan astronomers and observers from all over Italy explaining what will happen on Facebook.
It is an opportunity not to be missed because it certainly doesn’t happen every day. At dusk, therefore, the eyes were pointed to the southwest. You will see the two planets very close, in what is called the “Christmas Star”.
