Legendary stories about stars

The stars are hanging in the sky, giving off wonderful light. Then let's learn about the legend of the stars.

Legendary stories about stars

1. The story of the stars

Was it like this in ancient times? Beautiful? Story: When the stars in the sky fall into the world, a person will die and a person will be born.

Thousands of years have passed. Beautiful? Our story gets better with the passage of time: Meteor has a beautiful name called Meteor. When it glides across the sky, people can make a wish to it, and this wish will come true.

Looking at the stars in the sky, I feel that they are so small and so close to me. However, in fact, it is far away from yourself, many times larger than you think. Its appearance gives people an illusion.

People on the ground pin their hopes on distant stars, hoping that they can help them realize their wishes. The stars in the distance are also full of yearning for mysterious human beings.

Among the stars, they also have groups like human beings, the so-called society and life. With a huge living group, there will be disputes, entanglements and contradictions. Every star, like everyone else, has his own thoughts and feelings. They also have joys and sorrows and death. So, among the stars, they also have good stars and evil stars? They will do whatever it takes to survive, just like humans.

But because of the distance, the stars and humans can't see each other, so they both give each other a beautiful story. In the world of stars, there has been a story that there is a planet called the earth in the distance. On that planet, there is something called life, and every life will create miracles, so there are many things that stars don't have. If any star is lucky enough to meet the so-called fate, they will help the star achieve his wish.

There is such a star among the stars. From birth, it heard this beautiful story. Since then, it has stretched its neck as much as possible every day, hoping to meet mysterious life.

Tick-tock? Thousands of years later, the stars are still searching every day, but they have not met life once. One day, the star met an old but wise grandfather. The star asked Grandpa Star how he could meet life on the earth. Grandpa Star didn't answer the question of Star, but told it a story: On a planet called Earth, life living there has always had a beautiful story. Whoever sees a meteor fall at night can realize his wish. After listening to this, the star was puzzled.

Tick-tock? Thousands of years have passed, and the stars are thinking about Grandpa Star's words every day. One day, the star saw this sentence in a book:? People always like to make things mysterious and pin their hopes on mysterious things. ? On that day, Star finally understood what Grandpa Star said.

Thousands of years have passed, and the stars are thinking about Grandpa Star's words every day. Finally, one day, the star is about to finish its life. When it slowly deviated from its orbit and headed for an unknown planet, it suddenly realized one thing. People always like to mystify things and pin their hopes on things that have become mysterious. On that day, when the star was about to end its life, it finally understood what Grandpa Star said. ?

Basic introduction of stars

1 The planet itself does not emit light, but what we see is the sunlight it reflects.

A star is a big celestial body like the sun, which will react on its own and radiate energy into space in the form of light.

Comets are like Halley's comet. The light we see is the phenomenon that the tail of its material is melted when it passes through the solar system. So the comets we see often have long tails. Most of the stars we can see at night are stars, and some of them are planets in our solar system, such as Venus, Mercury and Mars. The luminous principle of stars is similar to that of our sun. Most of them release energy in the process of hydrogen condensation into helium nuclei, and some of them release energy through helium fusion. Just because they are far away from us, they look like a gentle little star. In fact, they are much bigger than the sun. The planet looks bright because it reflects the sun's light, but it only absorbs the light near us and looks brighter than the stars.

The sun looks as big as the moon in the sky, with a diameter of 6.5438+0.392 million kilometers, which can hold 6.5438+0.3 million earths. Coincidentally, the diameter of the sun is about 400 times that of the moon, but its distance to the earth is about 400 times that of the moon, so it looks about the same size.

As a satellite, the moon is one of the 66 satellites found in the solar system. There are only four or five satellites larger than the moon, of which Ganymede, the largest in diameter, is more than 5200 kilometers in diameter. Most of the others are only tens to hundreds of kilometers.

As a planet, the earth ranks fifth among the nine planets in size and is considered to be of medium height. The largest Jupiter is 1300 times that of the earth, the brightest Venus is almost as big as the earth, and the red Mars is only one-eighth as big as the earth.

Planets and satellites are really small compared with the sun, the mother of the solar system, just like sesame seeds and watermelons. The sun is unique in the solar system. However, the dazzling sun will be eclipsed by the stars that look only the size of a needle tip-there are only hundreds of millions of them.

One of the most common stars is only of medium size. Antares in Scorpio is 600 times the diameter of the sun, and Betelgeuse in Orion is 900 times the radius of the sun. One star in Cepheus is bigger, and its radius is 1600 times that of the sun, reaching 1 1 100 million kilometers. If placed in the position of the sun, even Jupiter will be in it.

But most of them are red giant stars in the late stage of evolution, and their density is extremely small.

Of course, some stars are much smaller than the sun. White dwarfs at the end of stellar evolution are smaller than the earth, ranging in diameter from several hundred kilometers to several thousand kilometers. The smallest stellar neutron star is only 10 km in diameter. Don't underestimate these two little stars. Although they are small, they are very massive, generally equivalent to the sun. So their density is amazing. The density of neutron stars is 6.5438+0 million times that of the sun.
