From this, it is clear that the velocity and speed of the moon in the sun's reference frame do change. Remember the moon is accelerating as it is undergoing circular motion so it's velocity does change. Though there is no need for the moon to stop in either reference frame.

Also why do you take the 2288 MPH figure to be that at full moon and not say, at quarter moon or new moon.

Just as a side question what is your background in physics? I just don't want introduce concepts too advanced or to simplify my replies if you already have that sort of understanding. [[User:PeterIceHockey|PeterIceHockey]] ([[User talk:PeterIceHockey|talk]]) 16:03, 16 December 2016 (EST)
