Depends on where the debris field is located. If it’s further out (about the orbit of the Moon), it shouldn’t be a problem except rarely to extra-terrestrial flights (that is, missions outside of the Earth’s sphere of influence, not aliens). Remember, space is mostly empty, even in ‘crowded’ areas like the asteroid belt. If it does impact the Moon, most of the debris will either fall back to the moon, end up burning up in entry of the Earth’s atmosphere, or (possibly) escape the Earth’s gravity well and end up in solar orbit elsewhere. If it just breaks up on it’s own, a less likely (but far more cool) scenario would end up with the Earth temporarily having a small ring system for a while.

We just make bigger debris, problem solved.

All the debris orbiting the earth is going to be a major obstacle to regular space travel.

Perhaps if she were more than pony. More than life. Perhaps if she were a god, she could command it…
 
 
TO KNEEEEEEEL!

Not the first time it’s happened either. It’s going to either disintegrate eventually or leave us. Maybe even crash into the moon but the chances of something fun like that happening are next to none.
 
The fun being the amount of additional debris being ejected posing a potential danger to us.

Imposister.

So in other words, Luna wants this asteroid to…  

I think it’s even smaller than a potato if compared to the Moon, as it’s only about 40-100 meters in diameter. Makes a good target for capturing practice, though.

farce, not “farse”

Imagine this: Nightmare Asteroid 2016 HO3 XD

Let’s be honest here: many scientists doubt that Moon can be called “satellite” (aka “moon”) of Earth. It’s more like a part of double planet system.

Oversensitive, much?
