I defend the planet from asteroid collisions

“There are a whole bunch of tens of millions of asteroids within the Photo voltaic System, nearly all of that are in the principle belt between the orbits of Mars and Jupiter. However a few of these asteroids, both via collisions, or via gravitational results or different processes, find yourself in new orbits that come near or cross Earth’s orbit. Presently, astronomers suppose that there are greater than 36,000 of those near-Earth asteroids, and at the very least 2,400 of these are thought of doubtlessly hazardous, as a result of they might strike Earth.
