For the first time in 800 years, Saturn and Jupiter "combined" at close range. Where can we see it?

65438+February is coming, and there are many astronomical wonders in the world, such as Venus and the Moon, Gemini meteor shower, total solar eclipse, Jupiter and so on, but one astronomical wonder is very rare, that is, Saturn and Jupiter, which was staged on February 2 1 day in 2020, and the countdown is really rare.

According to the public explanation, this astronomical event is very rare in history. The meeting time of these two planets is very short, which will only happen once every 20 years, but this time Saturn and Jupiter will meet at close range for the first time in 800 years, so many people have never met them. If there is a chance to see it, and this time Jupiter and Saturn merge, it is the first close encounter between Saturn and Jupiter in 800 years.

Do you see it? Today's rare astronomical wonders, as long as the celestial bodies are good, can be seen in any corner of the world, Jupiter and Saturn will "meet" together in the night sky, so that they look like "twin planets." Of course, there is a concept of "twin planets", which we can explain briefly. That is to say, the two celestial bodies that meet the definition of planet are similar in size, and their center of gravity is not inside the main celestial body, and they revolve around each other, forming two obvious "combined" states, similar to those of planets and satellites, but it should be noted that these are not satellites and planets, but two planets, which is the difference. The statement of two planets also comes from the mutual revolving between stars.

Although Jupiter and Saturn may have been in relatively close motion during our observation, when Saturn and Jupiter merge, the distance between them will be only one-fifth of the diameter of the full moon, and the distance between the two stars will be 0. 1 degree, which is completely close to the resolution limit of the naked eye, so if weather permits, everyone can prepare for observing this astronomical wonder in advance. Moreover, we also said that "this phenomenon can be observed anywhere on the earth", that is to say, it can be seen anywhere in the world, and the best position is near the equator. The higher the latitude, the shorter the time for observers to see the intersection of binary stars. Therefore, on the contrary, the observation time in the low-dimensional region is longer.

If we miss this time, those who are waiting to see Jupiter and Saturn so close from a higher position in the night sky will have to wait until1March 980 15. After that, Jupiter and Saturn will not meet at such a close distance until some time after 2400 years. Therefore, it will be 400 years before we can see the recent wonders of the conference. Even at that time in 2080, this standard could not be reached. I believe that many people may only encounter this once in their lives, so we should seize the opportunity. On June, 65438+February, 265438 +0, the earth star was in Capricorn, and Jupiter just passed the south side of Saturn, and the sight distance was only about 0. 1 degree.

This is the basic situation of Saturn and Jupiter this time. On the whole, this is an "excellent" astronomical spectacle. Of course, in essence, Saturn and Jupiter are actually a phenomenon of "hiding" or "ling" of planets, so they are not in a harmonious state, which is equivalent to a shielding pattern, forming this spectacle. This is how Jupiter and Saturn met this time. Many people may be thinking, is there something important happening at this time? In fact, this astronomical spectacle is normal, nothing strange, and there are still many rare wonders we see every year.

For example, what we call "super blood moon" and "super blue moon" are actually some normal astronomical wonders, but in different parts of the world, we see different wonders every time, which forms a misunderstanding for everyone. Every time something unusual or rare happens, it will be considered as an "unknown" problem by many people. Now we can also see that the earth is still running steadily without any change.
