Could the eight planets be aligned in the same straight line? What is the cycle?

It is impossible for the nine planetary systems to actually be connected, because each planet has an irrational number in its orbital period, and there is no common factor at all, so it is impossible to connect in a line, and this possibility is so low that it is difficult to appear even in the lifetime of the universe.

But there is another kind of large planetary connection, which is to see the planets visually connected on Earth. But if we define it in this way, the eight planets are connected at any time, because all the planets are located in a disk called the ecliptic, and the earth is also in this disk, so the ecliptic plane becomes a line on the earth, the ecliptic, and all the planets are located in this line.

As long as the major planets are in 90 degrees of the ecliptic, they can in fact be called alignments, but the international practice is to be located at 26 degrees of the ecliptic or less.

If the ecliptic of 10 degrees is used as the standard, there have only been three times in the past 6,000 years when the eight major planets have been connected in a line.

Don't think that 10 degrees is small, the moon is only degrees.

The eight stars don't know, but Pluto's orbital angle is not the same as the other eight. So, the Nine Impossible.

No way! , the ecliptic angles on the horizontal line are different, and so far there is no documented record of the eight planets on the same line.

I think it's possible, but it's just a pitiful odds.

However, the Nine Stars have appeared in history.

Since 780 A.D., humans have experienced the Nine Stars only 15 times.

Nature in the Encyclopedia of Chinese Teenagers. The environment is well documented.

The eight planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune in descending order from near to far. Mercury is 57.91 million kilometers from the Sun, Venus is 108.2 million kilometers from the Sun, Earth is 149.6 million kilometers from the Sun, Mars is 227.94 million kilometers from the Sun, Jupiter is 778.33 million kilometers from the Sun, Saturn is 1429.4 million kilometers from the Sun, Uranus is 287099 million kilometers from the Sun, and Neptune is 450.4 million kilometers from the Sun.

The eight planets refer to the eight large planets of the solar system, according to the distance from the sun from near to far, they are Mercury ( ) Venus ( ) Earth ( ) Mars ( ) Jupiter ( ) Saturn ( ) Uranus ( ) Neptune ( ) Most of the eight planets also have the same rotation direction as the direction of revolution. There are only two exceptions: Venus and Uranus.

Venus rotates in the opposite direction to its orbit, while Uranus rotates "lying" at an angle of 97° to its orbit.

Definition of planets: first, celestial bodies that must orbit stars; Second, the mass is large enough to rely on its own gravity to make the celestial body spherical; The third is that there should be no other objects in the vicinity of this orbit (clean up other objects in its orbit). According to this division, there are only eight planets in the solar system: water, metal, earth, fire, wood, and earth, plus the king of heaven and the king of the sea.

In descending order from near to far, they are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune.

Now the eight planets of the solar system are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. aqui te amo。

Water, metal, wood, earth, earth, fire, king, sea king.

The eight planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune in descending order from near to far.

As a planet, there are three conditions to be met:

Orbits the star in an approximately circular orbit.

The mass is large enough to rely on its own gravity to make the celestial body spherical.

Gradually clears celestial bodies in the vicinity of its orbit.

Pluto is excluded from the big planets and called dwarf planets because of the third inconsistencies and the fact that Pluto's moon (Charon) is so large that it forms a double planetary system.

How to memorize the eight planets:1. Simple notation.

The five elements (gold, wood, water, fire, earth), sea, land and air (sea king, earth, heavenly king).

2. The first word of the name.

Water, gold, earth, wood, earth, heaven and sea. It's a little long, but it's easy to remember.

3. Imagine memory.

It's a bit far-fetched, but the memories are kept for a long time.

The crystal ball, burned wood, turned into earth, the ends of the earth.

4. Poetry memorization methods.

The water floods the golden mountains, the fire burns the wood and the scorched earth, the sky and the sea become one, and the vast solar system.

The fire burns the wood-scorched earth, so there is an asteroid belt between Mars and Jupiter.

The sun is the center of the solar system, the eight planets are rotating around the sun on the surface, if you look more closely, the result is not so, the representative planet is Jupiter, after the rotation trajectory of Jupiter is accurate, scientists have found that Jupiter and even the sun are revolving around a point in the solar system that does not exist, and this point is called the "center of mass", the main reason why Jupiter looks out of place in the solar system is that its mass is large enough, Its enormous mass even moves the sun and it does the same thing.

Jupiter, one of the eight planets, does not revolve around the Sun because of its massive mass and strong gravitational pull, so it is "irregular". There are too many wonderful rules and phenomena in the universe waiting for us to explore, and human wisdom is slowly breaking through.

As of March 29, 2021, there are eight planets, and they are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune in descending order from near to far.

On the afternoon of August 24, 2006, at the 26th session of the International Astronomical Union, Resolution 5 was adopted, and astronomers voted to officially classify Pluto as a "dwarf planet" and remove it from the list of "planets". Most of the eight planets also rotate in the same direction as their orbit. There are only two exceptions: Venus and Uranus.

Venus rotates in the opposite direction to its revolution. Uranus, on the other hand, "rolls" in orbit.

The order of the eight planets of the solar system is Mercury – Venus – Earth – Mars – Jupiter – Saturn – Uranus – Neptune. The solar system is made up of the sun, planets, interplanetary matter, asteroid belts, asteroid families, comets, Oort clouds, dwarf planets, etc. A planet usually refers to a celestial body that does not emit light of its own light and orbits a star, often in the same direction as the rotation of the star it orbits.

In order of distance from near to far, they are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

In terms of size, Jupiter, Saturn, Uranus, Neptune, Earth, Venus, Mars, and Mercury are the sizes. By the way, there are also memory formulas to help with memory.

Among the eight planets, Mercury, Earth, Mars, Jupiter, Saturn, and Neptune have the same direction of rotation and revolution, but Venus and Uranus are different, and the autobiography and revolution of Venus are completely opposite.

Neptune. The orbital period has a certain relationship with its distance from the sun, the farther away from the sun, the longer its orbital period, among the eight planets, Neptune is the farthest from the sun, so its orbital period is the longest. To include dwarf planets such as Pluto, it is Pluto.

Neptune is the eighth planet orbiting the Sun and the fourth largest object in the Solar System (in diameter). Neptune is smaller than Uranus in diameter but has a greater mass.

Basic data. Orbital orbit: 4,504,000,000 km (astronomical units) from the Sun Orbital inclination: degrees.

Planet diameter: 49,532 km (equator).

Mass: kg.

Rotation period: about 22 hours.

Orbital period: about one Earth year.
