Has planet Earth ever occupied the same point in space more than once?

This requires a bit of explanation... The Earth orbits the sun once a year and I used to think that it would come back to exactly the same point in space after completing each orbit. Then I realised that the sun is also moving, around the centre of the galaxy... Then I realised that the galaxy is also moving,... show more This requires a bit of explanation...

Then I realised that the sun is also moving, around the centre of the galaxy... Then I realised that the galaxy is also moving, etc.

I can't get clear in my head what shape is the path that the Earth is therefore making through space... It clearly can't be a circle or an ellipse...

Now I'm wondering if the Earth has ever been in the same place twice...

What's the answer???
