Question

How does the Giant Impact Hypothesis resolve impulse for orbital insertion?

Answer 1

This is not necessarily the case. The jury still seems to be out as to the impactor's origin. While it may have been an object with a unique orbit about the Sun, others propose that it was captured within either the L4 or L5 points for the Earth-Sun system (indicating that it wouldn't have kept going). My question is more of the "what goes up must come down" variety. If the material was simply blasted from the surface of the earth it would either have enough velocity to escape the influence of the Earth, or it would eventually fall back to the Earth as meteoric material

Answer 2

Explanation:

4. The giant impact hypothesis states that when the Earth formed, about 4.5 billion years ago, a nearby newly-formed object half as wide as Earth collided with it. A fraction of the debris from the crust and mantle (from both Earth and the colliding object) spewed into orbit around Earth and accreted to form the Moon.
