How did the horoscope come about? 40

A constellation is a group of stars in the sky that are projected on the celestial sphere in close proximity. Different civilizations and historical periods may have different divisions of constellations. Most of the modern constellations evolved from the traditional constellations of ancient Greece, and the International Astronomical Union accurately divided the whole day into 88 constellations.

Have you ever had the experience of lying on the grass and looking at the clouds? The clouds in the sky floated slowly in one direction like white marshmallows. Sometimes you will suddenly notice a strange pattern in the clouds, which may be a human face or some kind of animal.

Actually, constellations are patterns that people imagine after seeing the stars in the sky according to the relationship between their positions. It's like a game where you connect dots with a line and end up forming a pattern.

Humans have been searching for pictures in the sky since time immemorial, and the Sumerians have been drawing constellations for at least 4,000 years ago. It's no surprise that people draw all sorts of interesting patterns they see. For example, nomadic accounts of the stars often appear in the shape of animals, and sailors who often wander the sea will find compass patterns in the sky.

Astronomers believe that people can gain some useful information by discovering familiar patterns in the starry sky, and the most important of these is to determine the direction and position.

Observing the pattern of the stars also helps people to ** the mysteries of the sky. Ancient astronomers divided the sky into different regions, each of which consisted of a group of stars called constellations. People will name each zodiac sign and make up some stories about them.

Different constellation patterns, different cultures about the stars have, the results of the advent of not only that, but the description of the constellation is very strange. We now know that people saw a group of stars around this group of constellations, and when ancient Egypt saw a star, they thought of a man lying down, and this ox was a bull at the same time, and behind the ox was a hippopotamus being chased by a hippopotamus, and this hippopotamus was walking on two legs, and the hippopotamus had a crocodile on its back!

In modern star charts, the stars in the northern and southern hemisphere skies are divided into 88 constellations, most of which date back to 2600 BC.

Stars in the same constellation may not seem far apart, but this is not the case, and the distance between any two stars can be trillions of kilometers. But distant stars can be very bright, so they look very close to other stars that are close to us, but faint.

But the horoscopes are not constant as there are always stars born or dying and are in constant motion. A million years ago, the Big Dipper (the group of seven stars in the constellation Ursa Major) was shaped less like a spoon and more like a spear. It is conceivable that in a million years, the stars in the sky will be completely different, and people in the future will probably rename the constellations.

Finally, let's imagine one. Under the night sky on other planets. In another distant solar system, there may be an Earth-like planet, and our sun will become a small star in their eyes, playing an important role in a constellation, or the tail of some strange animal!
