Based on the amount of material in the asteroid belt.....

.....is it possible to calculate how big the planet was that created it?

If you believe in the "the asteroid belt is the remnants of an obliterated planet theory". Makes perfect sense.

@handyjayjr:

I think it's more than just 1 obliterated planet

There's whatever crashed into as well but what do you mean by more than one?

@handyjayjr:

Never mind I just look up the size and length and realized it's more likely to be just one planet.
