Could an asteroid destroy Earth?

Scientists say that our planet is durable enough to withstand a strong impact but living organisms not so much.

Like the dinosaurs that existed on Earth for over 160 million years became extinct due to the fall of a space rock on our planet.

Around 65 million years ago, an asteroid with a diameter of at least 6 kilometers crashed into Earth causing earthquakes, tsunamis and climate disasters. Then 75% of the life on the planet was lost.

Experts say it would take a rock impact of roughly the same size to destroy the planet. But this does not apply to the extinction of life. NASA claims that a rock with a diameter of 150 meters is considered a threat. If such a rock falls on a city, it can completely destroy it as well as its immediate area.

But if the rock is one kilometer in diameter then it will bring total destruction. It will cause global climate disasters and wipe out life. Initially there will be massive impact heat that will destroy everything around. Then the dust that will be present in the atmosphere will prevent the light of the Sun from reaching the Earth with the consequence that the plants will not be able to carry out photosynthesis. And that will mark the end of life.
