What's the biggest, most spectacular asteroid collision the moon could save us from?

+0
−0

An asteroid collision big enough and fast enough to see a massive ejection of rock and moon-chunks, from the surface of the earth AND not wipe out the population of the planet.

What size and speed of asteroid would it take to have a majorly visible and spectacular impact on the moon?

What after effects would this have? What would the moon look like? Would there be any minor effects in the earth?
