All the constellations in the sky, how many constellations are there in the sky?

A long time ago, astronomers divided the sky into many areas with imaginary lines and named them accordingly. At present, the entire sky is divided into regions, also known as constellations. Each star in the sky is divided into six scales according to its brightness, called magnitude.

The brightest is the first-magnitude star, followed by the second-magnitude star, the third-magnitude star, and so on, the faintest that can be seen by the naked eye is the sixth-magnitude star. In this way, we can count the stars in each constellation according to the magnitude of the constellations throughout the day, and we can count the stars that can be seen with the naked eye in the whole sky. The result is:

first-class stars; second-magnitude stars; third-magnitude stars; fourth-magnitude stars; fifth-magnitude stars; There are six magnitude stars, all of which add up to a total of stars. In fact, there are far more stars in the sky, and the vast universe is only the tip of the iceberg that human observation recognizes. A lot of stars are just too far away from us.

Some distant galaxies appear to be nothing more than a vague speck of light in the most advanced astronomical telescopes, but they contain thousands of stars. Our solar system is only a tiny part of the Milky Way, which has more than 100 million stars, but it is only a tiny fraction of the universe. The universe is endless, and how many huge galaxies there are, and how many beautiful stars there are, has always been an unsolved mystery.

Therefore, the visible stars can be counted, and the invisible cannot be counted. Summary: Astronomers divide the entire sky into constellations, and the first star in each constellation is divided into six grades according to its brightness.

We can count the stars that we can see with the naked eye, and the stars that we can't see are countless.

Astronomers divide the stars in the sky into 88 constellations according to their regions. Among them, the northern sky (bounded by the celestial equator) has 29 constellations; There are 46 constellations in the southern sky and 13 constellations in the north and south of the celestial equator.

There are 88 constellations in the whole sky.

In order to facilitate research and observation, people divide the starry sky into several regions, each region is a constellation, just as a province is divided into many counties and cities, and each constellation is given the name of a person, animal or instrument in a mythological story. Western constellations began as early as the Babylonian era, to the second century Ptolemy (Ptolemy) when he divided the whole day into 48 constellations, and then successively increased about 40, but the constellations continue to change and supplement, in 1930 the International Astronomical Society announced that the whole day was determined to be listed as 88 constellations and constellation boundaries, including 28 in the north sky, 12 in the ecliptic, and 48 in the south sky.
