In October of 2025 astronomers confirmed the existence of five asteroids that had been hidden by the glow of Venus. They also confirmed these asteroids and possibly others could someday threaten the Earth.
 

There have been many predictions of the aftermath of large asteroids hitting the Earth. None of these scenarios are good. Most likely such an event would plunge the Earth into what scientists call an Impact Winter. However, if they all hit and are of sufficient size, Earth could be looking at the possible sixth extinction event in its history.
 

This is known as a Level 6 event.
