How many stars are there in the sky?

Astronomers divide the stars in the sky into 88 constellations by region. Among them, there are 29 constellations in the northern sky (bounded by the celestial equator); There are 46 constellations in the southern sky and 13 constellations across the celestial equator. As long as we are patient, we can count the stars in one constellation and then the next constellation, so that we can count the stars that can be seen by the naked eye. According to the results calculated by astronomers, there are 6 stars of magnitude 0; 1 Isometric14; 46 second-class stars; 3 stars134; 458 4 stars; 5 stars1476; There are 4,840 6-level stars ... * * * The total number of people does not exceed 7,000.

If we use binoculars, the situation will be different. We can see more than 50,000 stars even with a small telescope. The largest astronomical telescope in modern times can see more than 654.38 billion stars.

In fact, there are many more stars in the sky. The universe is endless, and what modern astronomers see is only a tiny part of it.
