To be more explicit, it is the intersection of a spherical surface (celestial sphere) and the ecliptic plane; in terms of geometry, it is the average orbital plane containing the earth orbiting the sun. The ecliptic plane should be a stable and unchanging ecliptic plane, which is

The plane of the angular momentum sum of all planetary orbits, and the moon should be the main influencer. The ecliptic plane is inclined with the unchanging ecliptic about 1.5°. In fact, it can be simply understood as the plane where the earth's revolution is...

Geometry is a complex mathematical calculation, so here we can assume that the ecliptic is an unstable plane. In fact, the plane of the ecliptic is in a fluctuating state, but these subtle errors can be corrected through a series of complex operations in geometry.

Then, Qin Emperor Ying Zheng transformed from an astronomer to a mathematician. Through a large number of geometric operations, using the angles perpendicular to other stars, he began to silently calculate the specific position of the moon above the earth in his mind.

The moon orbits the earth in an elliptical orbit. The great circle obtained by this orbital plane on the celestial sphere is called "White Dao". The white Dao plane does not overlap the celestial equator, nor is it parallel to the ecliptic plane, and its spatial position continues to change. The period is 27.32 days.

The moon's orbital plane (white path plane) and the ecliptic plane (earth's orbital plane) maintain an angle of 5.145396°, while the moon's rotation axis is at an angle of 1.5424° with the normal of the ecliptic plane. Because the earth is not a perfect spherical shape,

Instead, it is relatively uplifting at the equator, so the white path surface is constantly precipitating (that is, the intersection with the ecliptic is rotating clockwise), completing a week every 6793.5 days (18.5966). During this period, the white path surface is relative to the earth's equatorial plane (the earth's equatorial plane is 23.45.

The angle of ° inclination to the ecliptic plane will vary from 28.60° (i.e. 23.45°5.15°) to 18.30° (i.e. 23.45°-5.15°). Similarly, the angle between the moon's rotation axis and the white path will also be added.

6.69° (i.e. 5.15°1.54°) and 3.60° (i.e. 5.15°-1.54°). These changes in the lunar orbit will in turn affect the inclination angle of the earth's rotation axis, causing it to swing ±0.00256°, which is called a sport.

.

Relatively speaking, the moon's spatial changes are smaller and easier to calculate through mathematical methods. After Qin Huang Ying Zheng's hard work and complex calculations, Qin Huang Ying Zheng finally got the accurate data of the location.

As he got his wish, he couldn't wait to peel off the power representing Taiyin from his body. He used his body to transform into four images and gathered the Taiyin and Sun in one body. If he wanted to arrange a small circle of great formations, he naturally had to give it to the heavens.

The power of each star should have, so it is indispensable to strip away the power of the moon and turn it into the moon.

However, from the perspective of Yan Zheng and others, they could not see any tricks. Yan Zheng and others only saw a black shadow flying out of Qin Huang Ying Zheng's body. The black shadow was as fast as water flowing.

Flying quickly to the sky of Qianjin Tower, Yan Zheng and others felt that it was dark in front of them. The black shadow had already merged into the dark background of Qianjin Tower Hall. The black shadow did not merge into the dark curtain of Qianjin Tower Hall Hall, but

Turned into a black star.

As long as people on earth are not fools, they know something. The moon itself will not shine. The moon basically has no water, so there will be no weathering, oxidation and water corrosion process on the earth, and there will be no sound transmission. There is a quiet world everywhere.

The moon itself does not shine, the sky is always dark, and the sun and stars can appear at the same time. The light emitted by the moon comes from the sun. It reflects the sun's rays and makes people feel that it is shining, so in the absence of the sun, the moon

It's just an unknown dark star in the universe!

The dark background of the Qianjin Building hall perfectly creates an atmosphere of the universe background. The moon, which was replaced by the power of Qin Huang Ying Zheng, was perfectly hidden in the darkness of Qianjin Building!

Looking down at the confused people around, Qin Emperor Ying Zheng was not only a little proud, but especially when he saw Li Jiancheng's ignorance in his eyes, Qin Emperor Ying Zheng's pride became a little higher.

At this moment, Qin Emperor Ying Zheng didn't have to see through Li Jiancheng's mist, he knew that Li Jiancheng didn't understand what he was doing. The black fog was written with the word ignorance! What else is in front of the other person, in the other person's eyes

Is it more exciting to engage in conspiracy openly underground?

The answer is no. At least now, Qin Huang Ying Zheng felt as comfortable as drinking a big bowl of iced sour plum soup in the day of the summer. The whole ghost was comfortable from the inside out, and the pores on his skin that had long been weathered and dead seemed to be open at this moment.

It made his body a little light ~

Will it be farther away if other stars appear in the moon?

Thanks to the inspiration of positioning the moon, Qin Emperor Ying Zheng was very enigmatic, as if a clear spiritual energy swept across his spiritual platform, commonly known as enlightenment.

He was limiting his eyes to the differences between ancient and modern stargazing methods. He was brave enough to open up his thinking, not sticking to ancient and modern times, and looking for all ways to locate stars. This thought really made him find a way out, the earth

The sun is revolving around the sun for one year, but we who live on the earth do not feel like observing the sky. Instead, we see that the sun has been rotating in the sky for a year. The trajectory of the sun’s movement,

It is the eclipse we often talk about (the eclipse was originally named Tian Equator, but was changed to the eclipse in the Tang Dynasty).

The ancient Greeks evenly divided the zodiac into twelve sections. Because they worshiped the sun god Apollo, they "built" a palace on each section, which is the so-called "zodiac palace". Yes,

The real legend is different from the Saint Seiya. The zodiac sign guards not the goddess Athena, but his brother Apollo. The name of the zodiac sign is similar to the 12 zodiac signs near the zodiac sign, namely Aries

Palace, Taurus Palace, Gemini Palace, Cancer Palace, Lion Palace, Vascular Palace, Libra Palace, Scorpio Palace, Capricorn Palace, Aquarius Palace and Pisces Palace. These things are already clear to everyone, here,

There is no need to say anything more.

The word zodiac (zodiac) comes from the Greek zodiakos. In astronomy, the trajectory the earth circumference around the sun is called the "zodiac". The zodiac is 16 degrees wide and circumference around the sun is 360 degrees. The zodiac

The surface includes the orbits of all planets except Pluto, and also includes constellations, which are exactly about every 30 degrees, with one constellation in each range, totaling twelve constellations, called the "Zodiac Palace". The earth is on the zodiac

Run from west to east, and it is surrounded by the "day" every year. There are twelve constellations distributed on a belt on both sides of the ecliptic, and people on Earth can see them one after another within a year. In another ancient civilization, the ancient Babylonian civilization, it faces ten
