What is the probability of the eight planets collinear? Isn t the planetary alignment phenomenon a l

There is also a probability that the eight planets are collinear, but it is impossible to say how long the time will take, which depends on the respective trajectories of the eight planets, which requires cycle time.

The probability of the contribution of the eight planets is about 1; Eight stars in a row, this is not a legend that has really appeared in history; It is still possible, but it will take a certain amount of time and time.

I think this probability is still very small, and this phenomenon will only appear in **.

The eight planets are orbiting in their respective orbits. I want to have an eight-star alignment. This astronomical phenomenon is very rare, occurring three times in 6,000 years.

In fact, it is impossible for the eight planets of the solar system to be completely arranged in a straight line, because although the solar system has an ecliptic plane, each planet has its own plane when it orbits the sun, and it has a certain angle with the ecliptic plane of the sun, so strictly speaking, the eight planets cannot be completely in a straight line anyway, but from the vertical observation of the ecliptic plane of the sun, it is possible for the eight planets to be roughly arranged in a straight line in a fan-shaped region. This phenomenon is known in astronomy as a "planetary alignment", but when viewed vertically, it is not a complete straight line, and it is usually staggered.

After saying goodbye to school, do you remember the order of the eight planets in the solar system from the inside to the outside? The eight solar planets of "water, gold, earth, fire, wood, earth, heavenly king, and sea king" naturally revolve around the sun all the time. Miraculously, they "coincide", quite "tacitly", around the sun along the same direction from west to east, moreover, the eight of them are in the same plane, and all do a near-circular motion.

In this case, the eight planets will naturally not collide, so is it possible that the eight planets are collinear? The answer is entirely possible. After studying basic physics in middle school, we know the law of gravitation, and know that the eight planets of the solar system have their own orbital periods, and we can get the cycle time of the "planetary alignment" by calculating.

It is worth noting that the orbital coplanarity of the eight planets we are talking about is approximate, and there is absolutely no "exact" coplanar in the universe, and in the same way, what we call "planetary alignment" is also approximate, which refers to the situation that the planet is on one side of the sun, and the angle does not exceed 100 °.

In the past 6,000 years, it has only appeared three times. The cage is calculated as 3 occurrences every 6000 years, that is, 2000 times, and the probability is as low as . It may seem to us today that this is just a natural astronomical phenomenon, but for the ancients who could regard the "tengu eating the sun" as an ominous omen, the different numbers of planetary lines had different meanings.

The cycles of the three inner planets of Mercury, Venus and the Earth and the three outer planets of Mars, Jupiter and Saturn are of course different.

We can deduce the cycle time of the "planetary alignment" through the quantification of gravitational force, the probability is very low, from ancient times to the present, more than 6000 years, only 3 times, so about once in 2000 years, the probability is 2%, and there is a record of the phenomenon of planetary alignment in ancient times, so this is not a legend.

This probability is still relatively large, it may happen once in 2000, and the probability of occurrence is. So it is possible that the phenomenon of planetary alignment in ancient times is real.

Yes, it is entirely possible. After studying basic physics in middle school, we know the law of gravitation, and know that the eight planets of the solar system have their own orbital periods, and we can get the cycle time of the "planetary alignment" by calculating. But this is a very rare celestial phenomenon, just like a solar and lunar eclipse.
