An astronomical event that has not been seen by the inhabitants of the earth for 800 years. These are its details

Jeddah – by Talal Al-Hamoud – The inhabitants of the earth are waiting for a rare astronomical phenomenon that has not happened for 800 years, in the astronomical conjunction, which is considered to be one of the astronomical phenomena that occur due to the rotation of celestial bodies around the sun, when at least two Germans align in a straight line with the Earth, the phenomenon of conjunction occurs Expressed astronomically as the value of the celestial longitude of the two bodies.

Saudi astronomer Mulhim Hindi, member of the Arab Union for Astronomy and Space Science, has parted ways at Al-Arabiya.net: In a phenomenon that rarely occurs between the two gigantic planets (Jupiter and Saturn) , they do not connect except every 20 years, due to the long period of their rotation around the sun, therefore the buyer takes 12 years To complete a cycle, while Saturn needs 30 years, therefore Jupiter needs 20 years to catch up with Saturn.

He said: “Each coupling event between them will be the apparent distance, as we see them from Earth, is different. If the levels of the planets are close, the distance is as small as possible and vice versa, and when next pairing event between them on Monday evening December 21, 2020 AD, the apparent distance between them will be approximately 6 minutes. ” An arc (0.1 degree), and this very close distance has not occurred since AD ​​1623, but by that time they were close to the sun and the conjunction could not be seen, while the conjunction very close that the inhabitants of the Earth have seen dates back to 794 years (1226 AD), that is, before the invention of the telescope. This means that on December 21 this conjunction will be observed for the first time in history with this proximity between the two planets.

He said that Jupiter and Saturn appear these days after sunset, and that they are seen in the southwest at an altitude of about 20 degrees, which allows us to see them for two hours after sunset. sunset until they disappear behind the horizon.

He went on to say, “The conjunction can be seen with the naked eye, and they will appear close to each other like an elongated star, while the two planets are seen through the telescope with each other. ‘another with clarity of detail by the appearance of the distinctive rings of Saturn surrounding the planet and the four large moons of Jupiter with the appearance of clouds belting the surface of Jupiter. ”
