Among them, tomorrow 21 (Monday), we will be able to observe the state of “super-large approach” for the first time in 397 years. You can see that it is getting closer today, so take a look at it with your own eyes.
At the time of closest approach, it is a super-large approach approaching about 0.1 degrees (6 minutes), which is about one-fifth the diameter of the full moon. Jupiter and Saturn are bright enough to be seen with the naked eye, but they are close enough to be in the same field of view even when viewed with an astronomical telescope.
If you’ve observed Jupiter with an astronomical telescope, you may have seen four Galileo satellites, but you can see Saturn at a similar distance.
Jupiter and Saturn are approaching in a cycle of about 20 years, but this is the first time since 1623 that they have been this close, and it is the first time in 397 years. Next time it will be 2080, 60 years later.
Although called “approaching”, the two planets are not actually approaching, but the directions when viewed from Earth are the same and appear to be approaching.
Jupiter is a glowing planet even in the dark sky, and Saturn is also bright enough to be easily seen with the naked eye. Therefore, when these two planets are close to each other, it is difficult for modern people to imagine whether they “look like two” or “look like one” with the naked eye.
・ Jupiter and Saturn can be seen separately
・ Jupiter is so bright that it can only be seen as one
・ Jupiter and Saturn seem to be together
It depends on the brightness of the sky, so the appearance may vary depending on the area. Saturn is hard to see in the dark sky so I wonder what it will look like when it gets dark to a certain extent.
We are planning to run a quiz poll on Weather News to see what it will look like tomorrow night on the 21st. Please take a look.
