Astronomy cast ep 159

[wiggy]

Hi all,

In ep 159 pamela mentioned that part of the kuiper belt had been cleared out by something 30-70% the size of earth. Could this have been what came in and hit earth forming the moon? It would explain not being able to find it anyway ;)

Its possible, but was the Kuiper belt fully formed at the time of the earth collision.
