Did moon forming impact on Earth 4.3 byr. shiftet Earth's orbit significantly?

Did that impact shifter Earth's orbit alot and what direction?

We can not be certain of this at this point. It is known that a Mars sized object was in collision with this Earth and the debris of that impact has col est into the moon we see today. As to weather the orbital track of Earth has changed or was changed by that event would depend on angular velocity mass density and half a dozen other variables. Some of this Earths mantle and atmosphere may have been torn away. It was such a long time ago that other forces have long since destroyed any hard evidence of it. In its formating centuries this solar system was a hectic unstable place. Now some 4.5 billion years after we are attempting to learn what really happened then.

I recently read that that colision is the cause of Earth's axial tilt and so seasons but I dont know anything about change in orbit.

One of the leading ideas about this collision is that the other planet was in the same orbit as the Earth, but at one of the L4 or L5 Lagrange points. If this was the case, the orbit probably didn't change much.

We would expect that such a massive collision would change Earth's orbit and tilt by 1% or more. While the collision model has largely replaced several other ideas of the Moons origin, we perhaps have not yet considered the real way our moon came to be. Neil

We can guess, but we'll never really know.

Sorry if you think I am hijacking this thread.. I will put it back .. honest.
Excepting this early collision and the centuries of mayhem that must have followed.. Why is there life on this planet?

If the answer is because the conditions allowed it. Then I hasten to add,. We may never find life any where else. Because nowhere else has had this history.
I am of the opposing view. That life is rife. We are going to find it all across the galaxy. What do you all think?

Yes I agree.
