Are there any citation or documentation showing the measured degradation of the Moon's equatorial rotation velocity (thus affecting its moon's axial rotation)?

I am looking for the drift of the Moon's axis rotational speed, presumably over 10,000 years or more.

  • $\begingroup$ I don't know of a direct source, but my guess is that the best direct measurement data for determining this would come from Lunar Laser Ranging (LLR). I would start with something like this and follow the citation trails. There is some interesting information on indirect measurements found here, but no specific citations are given. $\endgroup$ – Dave Oct 12 '16 at 11:35
  • $\begingroup$ what is "axial rotation" ... ? $\endgroup$ – Fattie Oct 12 '16 at 14:52
  • $\begingroup$ Presumably the motion of the celestial body that is spinning such that an axis gets formed? But I get you, so I'm clarifying the question further. $\endgroup$ – John Greene Oct 13 '16 at 15:05
