Why are there a sun and a moon in the world?

Solar system. It is produced by the continuous accumulation of material in the primordial nebula. The sun is the center of this system and is the master of the solar system. It should be the sun that we have us. And we saw the sun. And there was the moon.

The sun is capable of emitting heat on its own.

As for the moon (it's just the name of a celestial body), it's a satellite of the earth (the earth belongs to planets that don't shine on its own). There are countless star systems in the universe like the solar system, and each star system has a star ie''The sun'', while many planets have moons that are''Moon'', that is, there is not only one sun and moon in the universe.

Some scientists say that our Sun also has a companion star, named Nemesis.

A solar companion is a hypothetical red or brown dwarf star located between 50,000 and 100,000 AU from the Sun.

and named after the goddess of revenge.

The theory that the Sun may have a companion star was first developed by Richard AMuller suggested that he had discovered a mass extinction on Earth.

There is a periodicity in time, about once in about 26 million years, to try to explain the periodicity of mass extinction.

The companion is estimated to have an orbital period of 26 million years before passing through the Oort cloud.

band time, interfered with the comet.

orbits that allow millions of comets to enter the inner solar system, increasing the chances of a collision with the Earth.

Why not. You don't realize that there is no sun. Will there be life on Earth? Will there be a bright side of the moon?

The solar system was created by the accumulation of material in the primordial nebulae. The sun is the center of this system and is the master of the solar system. It should be the sun that we have us. And we saw the sun. And there was the moon.

The Sun is a star that can shine and heat on its own, and the Moon (which is just the name of a celestial body) is a satellite of the Earth (the Earth is a planet and does not shine on itself). There are countless star systems in the universe like the solar system, and each star system has a star ie''The sun'', while many planets have moons that are''Moon'', that is, there is not only one sun and moon in the universe.

Some scientists say that our sun still has a companion star, named the goddess of revenge.

A solar companion is a hypothetical red or brown dwarf star located 50,000 to 100,000 AU from the Sun and named after Nemesis.

The theory that the Sun may have a companion star was first developed by Richard AMuller proposed that because he found that there is a periodicity between the branches of the mass extinction on the earth, about once in 16 million years, to try to explain the periodicity of mass extinction.

The companion is estimated to have an orbital period of 26 million years, and as it passes through the Oort cloud belt, it disturbs the comet's orbit, sending millions of comets into the inner solar system, thus increasing the chance of a collision with Earth.

The relationship between the Sun, the Moon, and the Earth is:

All three are stars of the solar system and belong to the same solar system.

The Earth revolves around the Sun.

The moon revolves around the earth, and the two form the earth-moon system, and the two revolve around the sun at the same time.

The Sun is the central body of the solar system and occupies the overall mass of the solar system. The eight planets, asteroids, meteors, comets, outer Neptune objects, and interstellar dust in the solar system all revolve around the sun, and the sun revolves around the center of the Milky Way.

Earth is one of the eight planets in the solar system, the third planet in order from near to far from the sun, and it is also the largest pre-mesoterrestrial planet in the solar system, with a distance of 100 million kilometers from the sun.

The Moon, popularly known as the Moon, is the Earth's only natural satellite and the fifth largest in the solar system.

1. The moon. The gas and dust that fly away from the Earth are not completely separated from the gravitational control of the Earth, and combine through mutual accretion to form an almost molten Moon, or they first form a ring and then gradually accretion to form a partially molten Moon.

In the early stage of the evolution of the solar system, a large number of "stars" were formed in the space of the solar system, and a celestial star equivalent to the mass of the earth was formed first, and the stars grew and merged to form a primitive earth through collision and accretion with each other. In the process of their respective evolution, these two celestial bodies formed a metal core dominated by iron and a mantle and crust composed of silicate, respectively. Since these two celestial bodies are not far apart, there is a good chance of encountering.

By chance, the small celestial body crashed into the Earth at a speed of about 5 kilometers per second. The violent collision not only changed the state of motion of the Earth and tilted the Earth's axis of rotation, but also caused the small celestial body to be fractured by the impact, the silicate crust and mantle were heated and evaporated, and the expanding gas flew away from the Earth with a large amount of shattered dust at a great speed.

The stocking material that flies away from the Earth is mainly composed of the mantle of the collider. The vast majority of the earth's mantle and crust materials evaporated, and the expanding gases flew away from the earth at a great speed carrying a large amount of shattered dust.

The metal core, which separated from the mantle when the impactor ruptures, is slowed down by the gas that expands and flies away, and is accretion to Earth in about 4 hours. The gas and dust that fly away from the earth are not completely separated from the gravitational control of the earth, and combine with each other to form an almost molten moon, or form a ring first, and then gradually accretion to form a partially molten large moon.

2. The sun. The sun was formed about 100 million years ago in a cloud of collapsing hydrogen molecules.

I simply divide the types of people I come into contact with into two main categories according to their traits: the sun type and the moon type.

People with the "sun" trait, they have a few things in common:1I care a lot about my appearance and image, and I am willing to spend money on clothing and grooming; 2.

Quite confident, love to show himself, become the core of the team and the people around him, and at the same time have high requirements for others; 3.Conquering the world by being strong on the outside, often empty or unconfident on the inside, how strong on the outside, how weak on the inside; 4.If you love to show your good side to others, you will feel "fake" and unreal; 5.

There will be a very utilitarian and snobbish side, which tends to be inflammatory, and ignores the "useless" people.

People with the trait of destroying the "moon" have the following characteristics:1It exudes warmth from the inside out, making people willing to approach, this power is more long-lasting, continuous and elegant; 2.

Unwilling to show himself, he prefers to be a deputy and take pleasure in fulfilling others; 3.looks like there is no quarrel with the world, and his heart is extremely strong, but he only compares with himself, not too much with others; 4.On the outside, he is often not confident enough, but he is firm in himself.

There are very few pure suns or pure moons, and often these qualities are mixed, and the inside and outside are not the same, and they are divided into four categories according to the combination of inside and outside:

1.People who are also the sun inside and the sun outside: this is also divided into the inner big sun and the outer small sun; The inner small sun, the outer big sun.

The former is still showing it, not too public, after a long time of contact, you will know how hot the inner Tai Tai Beiyang is, which often makes you stay away because you are afraid of burning yourself; The latter is strong on the outside, but not as strong on the inside. If it is really a big sun inside, the big sun outside, it will also shine brightly.

2.People with the inner moon and the outer sun: This kind of person belongs to the inner sage and the outer king, cultivating himself internally, and walking the royal road externally, many saints, sages, and kings belong to this kind of people, and they are the most perfect ones.

3.People with the inner sun and outer moon: Such people show gentleness and great inner ambition, a bit like a wolf in sheep's clothing, sometimes people are unguarded, and hurt themselves, and will use the kindness of many people to achieve their own goals.

4.People who are also the moon on the inside and the moon on the outside: such people are the same as the bridge on the outside and inside, warm and continuous, people are willing to approach, treat themselves and the people around them very nicely, be kind to others, believe in the beauty of the world, and rely on their own tenacity to solve many problems, and often the outcome is as they wish.

The sun and moon are some of the qualities that manifest themselves, and each person has different needs in each period, and they are different and can be converted into each other. No matter what your characteristics are, you will be happy in your heart when you are a person who is consistent on the outside and inside out.
