On Monday, December 21st (the day of the winter solstice), a unique and rare astronomical event will only be repeated every few decades, as the two largest planets in the solar system – Jupiter and Saturn – stick together in a phenomenon called the “Great Conjunction”, and the last time was This phenomenon happened in 1961, and the next time will happen in 2080.

The distance between the two bright objects will be a fifth of the moon’s diameter or the equivalent of a tenth of a degree (6 arc minutes), and it is close to two bright bodies that will make them a single body as seen with the naked eye.

At the same time, it will allow photographers and amateurs to capture the most beautiful image in one frame of the two great planets where Saturn’s rings embrace Jupiter’s cloud belts, and their moons overlap so that we can hardly distinguish which of the other is dependent upon the use of astronomical maps.

What is the pairing?
Because of the rotation of the planets in orbits close to inclination around the sun, that is, they are all almost applied except for a slight inclination between them (the inclination of the Earth is 23.5 degrees, the inclination of Mars is 25 degrees, the inclination of Saturn is 26 degrees), so they approach the sky from each other, they all revolve in the orbit of the zodiac And do not go beyond it, so some of them are seen close to each other infrequent accidents.

The meeting of two planets, or even any two celestial bodies, is known as a “conjunction” (Conjuntion), and the most famous conjunction of the sky is usually the crescent moon with Venus, which are usually seen shortly after sunset, followed by Venus and Jupiter being the two brightest planets in the sky, then Jupiter and Saturn, as well as the conjunction of the moon with one Brilliant star like Aldebaran, defenseless fish, and Lion’s heart.

And the most beautiful combination of all is the sun and the moon’s meeting in the famous phenomenon of eclipses.

Conjunction means the alignment of two or more celestial bodies in one line as seen from the earth (

How do we monitor the coupling phenomenon?
If you look shortly after sunset on any of these days towards the west, turning your face slightly to the left, then you will see one bright object, which is the white Jupiter, and if you peer over it a little, then you will see a less bright object than it is the planet Saturn.

These two planets have been approaching each other for days. The maximum close between them will be on December 21, and to monitor them; you only need to raise your eyesight high in the sky if you are lucky. You have double-eyed binoculars (Darbeel), or you can accompany someone Or a group carrying a telescope. You will have the opportunity to see the two planets in detail together and with one look.

Because of the Corona pandemic ban, some associations will organize a live broadcast of this phenomenon through their channels on social media. Individuals will monitor the phenomenon in small groups here and there in the Arab world and in all countries of the world as well; amateurs expect this event. They usually miss it only for compelling reasons like clouds and rain.
