RAS scientist Petrukovich: a kilometer-sized meteorite is capable of destroying the Earth from Ura.ru described what should be a meteorite capable of destroying the Earth. He noted that only celestial bodies a kilometer in size can do this.
“Large celestial bodies, such as the Tunguska meteorite, fall to Earth once every hundreds of years and cause destruction. If we talk about catastrophic impacts on the planet due to asteroids, then this, relatively speaking, happens once in a million years. Such large objects are visible from afar, we can calculate their orbits in advance and determine how close they are to the Earth, “the scientist said.
He also added that several small meteorites fall on the Earth every year. According to him, they do not fly into settlements and most often end up in the ocean, since it occupies two-thirds of the planet. Vladimir Surdin, a researcher at the Sternberg Astronomical Institute, added that they can be detected only a couple of hours before they hit the Earth due to their small size.
Earlier it became known that a meteorite pierced the roof of a house of a resident of the Canadian city of Golden, British Columbia, and fell on a pillow next to her. The woman did not understand how the stone got on her bed and called the police.
