Saturn and Jupiter will stage star attraction. What is it? Will it have an impact on the earth?

According to the astronomical weather forecast, there will be a very rare spectacle of brand image in 65438 on February 22 this year, and Jupiter and Jupiter will appear in Hengheng. From the earth, you will find that Jupiter and Jupiter are very close, just like digestion and absorption. Jupiter and Jupiter, the two protagonists of this rare horoscope, will appear at about 2: 30 on February 22nd, China 12. By then, the angular distance between them will be 6. 1, which is only about one fifth of the diameter of the sun, or the diameter of a child's full moon.

The engineer's title of Beijing Planetarium is Kouwen, 65438+February 2 1. Soon after sunset, we can see Jupiter and Jupiter in the southwest sky. At that time, their aspect ratio was already very low. Jupiter's chromaticity is too bright, about minus 2, so there is a Jupiter next to it, which is darker than it and should be a brighter star, that is, it will go down the mountain quickly after an hour's observation.

According to authoritative experts' calculations, the time for China to see this kind of astrology is 65438+February 2 1, which is short for more than an hour after dusk. At this time, Jupiter and Saturn look not much different from their latest time at 2: 30 am on the 22nd. In addition, if the observation is endangered by factors such as poor temperature at 2 1 night, you can also choose to watch it at dusk on the 22nd, when Jupiter and Saturn are still close.

Taking the earth as the management center, when Jupiter is the same as Jupiter's right ascension or yellow longitude, it is usually the moment when the two stars look the closest in the night sky when the stars produce such a malignant event of planetary matching. The match between Jupiter and Saturn is generally called Yamato. The period of Jupiter's rotation orbit is about 1 1.9 years, and the period of Jupiter's rotation orbit is 29.5 years. The average values of Jupiter and Saturn match every 19.6 years, and it seems that Jupiter is chasing Jupiter. In fact, the real distance between these two stars is at least 740 million kilometers. When they are far away, it reaches more than 865,438+0 million kilometers.
