This year is a series of extremely rare events in the field of astronomy and astronomy. There will be some such wonderful events this Christmas as well. The most important of these is the Jupiter-Saturn Conjunction which takes place on the 21st of this month (today).
Conjunction is the approach of two celestial objects to each other. A conjunction of two planets is simply an optical illusion, that is, their relative motion is observed as if they were close to each other. This Jupiter-Saturn Conjunction happens every 20 years, but we can’t see them all. Sometimes this also happens during the day and they are not all the same. This is due to factors such as the inclination of the orbits.
But this time we have the opportunity to see a very rare Jupiter-Saturn conjunction. It is said that such a rare Jupiter-Saturn conjunction was previously observed on March 4, 1226. At this conjunction, the angular displacement between Jupiter and Saturn is about 0.1 degrees. With such a small angle, the two planets can be seen together. This is called the Double Planet Effect. Jupiter and Saturn appear as dual planets for the first time since the Middle Ages, about 800 years ago.
How to observe this conjunction? Jupiter and Saturn can be seen above 25 Westin the western sky after 6 pm on these days. It can be seen that they are very close. The peak of this conjunction is December 21 (today) and we can observe it in the evening sky. If you look with the naked eye, you can see those two planets as a single object. If you use a telescope, you can see the angular separation of Jupiter and Saturn and their satellites.
Astronomers are eager to observe this opportunity as it is very precious and rare. 60 years later, on March 15, 2080, we will see the maximum opportunity for such an event to happen again.
