How many stars are there in the sky?

Stars are celestial bodies, which are glowing gas balls. Since ancient times, they have attracted human attention, agitated the mind, and attracted with dreams of distant worlds and civilizations. Why the stars seem so small The sun is the closest star to us, so we feel its light on ourselves much better than the radiance of other stars. Every day on Earth begins with sunrise and ends with the setting of this star. All others are located thousands, millions, or even billions of light years from us. It takes more than one year for a ray of light from a distant star to reach our eyes. In addition, the obstacle is air, which is in continuous motion and creates obstacles. Outer space is filled with debris, space.
