British media:In the near future, rare celestial phenomena will appear in the sky. The last time it appeared was in the Song Dynasty…
According to British media reports, this Christmas, astronomy enthusiasts will have a rare opportunity to see an amazing double star combination. The two largest planets in the solar system-Jupiter and Saturn will be in”close” contact, and the observation distance between the two stars will reach the closest value in nearly 800 years.
According to the British”The Mirror, this report of Jupiter and Saturn A phenomenon can be observed at the nearest moment after sunset on December 21.
Rice University Patrick Hartigan, the astronomer of China, said:“The parallel phenomenon of these two planets is inherently rare, occurring about once every 20 years, but this time it is extremely rare because the two planets look very close. This kind of double star combination still appeared before dawn on March 4, 1226 (China Southern Song Dynasty).”
Since this summer, the two planets have been there. The sky above the earth is close to each other, and the distance between them will be less than the diameter of a full moon from December 16 to 25.
Hatigen The professor explained:”On the night closest to the earth on December 21, they look like a pair of double planets (the two celestial bodies are relatively close in size, and the center of gravity between the two is not inside the main celestial body. Motion), the distance between the two planets is only 1/5 of the diameter of the full moon. For most telescope observers, in the same field of view that evening, the two planets and their largest satellites can be seen”
Although the best observation condition is near the equator, people with sharp eyes should be able to see this rare phenomenon with the naked eye.
Professor Hartigan said:“Before the planet sinks to the horizon, the farther the observer goes north, the shorter the time it takes for them to capture the conjunction.”
