Relative moon

Why does the moon seem to be moving in the same direction as me while I'm moving not the opposed ? Does that mean the the relative speed laws does not apply or it just the scale ? If so is there any mathematical way to describe it ?

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

I believe this is a result of the parallax effect and specifically lunar parallax. So you are right, the scale of both the moon and how far away it is compared to us makes it seem as if it is not moving away. Those links (to Wikipedia) include much of the math involved.
