#10 – We can see millions of stars
via fc02.deviantart.net complain
In fact, one can only about 6,000 starts. They shine so bright that we can distinguish with the naked eye. However, about half of them are over the horizon at night. Another part near the horizon is hidden in the haze. Therefore, in the darkest night, in the clear skies, we cannot see more than 2,000 stars. If the place of observation is lighted by artificial light sources, the number of stars is greatly reduced. Being in the big city, it is hardly possible to see one or two dozen of the brightest stars.
