When is nine planets's next winning streak?
According to the calculation results, scientists selected the "planetary conjunction" with more than seven planets in the past 300 years (1850-2150), and classified the planets with angles less than 13 degrees as "planetary conjunction". There are 17 such astronomical phenomena, the latest one.
At this time, Mercury, Venus, Earth, Mars, Jupiter, Saturn and Pluto are arranged in the range of 65438 degrees +02.6 degrees. The last "seven-star alignment" happened at 9: 00 on March 6th, 1965, and Mercury, Venus, Earth, Mars, Saturn, Uranus and Pluto were arranged within 9.3 degrees. At 4: 00 on February 6th, 2149th16th was "nine-star renju", and the rest16th was "seven-star renju".
Julian phenomenon
Nine-star alignment is an extremely rare natural phenomenon, which means that the nine planets are constantly orbiting the sun in their respective orbits. Their orbits are different in size, speed and period, and they are usually scattered in different regions of the solar system.
But after a certain period of time, nine planets will run to one side of the sun at the same time and gather in a fan-shaped area with a small angle. People call this phenomenon "Julian". To put it simply, when all nine planets are in a straight line on the same side of the sun, it is called a nine-star alignment.
