If asteroid YR4 hits our Moon, it’ll cause a bright flash and meteors as debris hits Earth, say scientists | BBC Sky at Night Magazine

I will never not be amazed at our little home in the Milky Way — and the cold, irrational nature of the universe. We aren't getting lucky every time an asteroid misses Earth, as some would think, because we only exist because our little blue marble is in just the right spot to have a low impact risk, compared to other planets. We're not lucky that asteroids always miss us. We're lucky that the moon is there to take a beating which just so happens to save earth.

I would say, however, that we are lucky that this is happening at a time when we can at least try do something about his asteroid.

The universe is a macabre and mysterious place. Really cool but also terrifying.
