Space rocks flying without a real purpose through space could one day wreak havoc on Earth.
But that’s hardly something you need to be worried about.
Some of these asteroids are automatically labeled “potentially hazardous” if they pass us by within a certain distance … but that distance can be millions of miles, so they often don’t really pose a threat.
