Another theory on the formation of the Moon

What is open to debate, we are assured, is not the impactor – that is a given. It is the size and speed of the impactor. However, as you'll be pleased to know, computer simulation has come to the rescue. The impactor was apparently faster and bigger than expected and struck a glancing blow.
