The limit of Bortle

The stars are somewhat similar to people: they are also born, age and die. Their luster depends on the surrounding stars. Just like people, they most often have a couple. Besides the sun - this star is always alone.

Sergey was an astronomer and dreamed of making an opening. Once he was lucky. He inhaled the nightly air and could not believe that he had just discovered a new special comet.
She was special because she was inevitably approaching the ground at a speed of over twenty -five kilometers per second.

Comet became a challenge to the world, a test of humanity, united in the struggle of strangers across the planet. There is very little time before the collision - can people understand who their enemy actually is?
