Hi
Today, in my physics class, a guy brought out something interesting.
We were talking about gravity and somehow the talk got to the moon. I have always thought that our moon's path is constant. That its not changing. Yet that "guy" said that every year (or so) the moons path has changd about 1-3 mm.
Im abit confused, since all the gravities are constant. I would understand IF
1) an object with the needed gravity to affect the moons path, and which is not yet affecting the moon, would start affecting it
2) every year different planets in our solar system would affect the moon differently (different speed on revolving around the sun, ending up affecting the moon gravitationally from different places).
Our teacher was also abit confused, but said he wouldn't start arguing about it since he hasnt hear of it really.
So my questions would be: Is the moons path changing? And if it is, why?
Thanks in advance,
