Lagrange?[edit]

Why no mention of Lagrange, who shared the 1772 Paris Academy Prize for work on the Theory of the Moon? 94.30.84.71 (talk) 22:11, 14 January 2013 (UTC)[reply]

Tidal acceleration[edit]

This article doesn't clearly discuss tidal acceleration, which has been an important part of lunar theory since it was noticed by Halley in the late 17th century. A clear presentation of how this long term secular perturbation relates to other aspects of lunar theory seems appropriate. --SteveMcCluskey (talk) 15:18, 10 July 2013 (UTC)[reply]

Barycenter[edit]

Is it worth mentioning barycentric coordinates (astronomy). i.e. when was the barycenter of Earth-Moon first reliably/reasonably known? Did that help in the development of lunar theory? I dont know the answers to those questions. Sorry if this isnt relevant. John Vandenberg ^(chat) 06:33, 7 January 2014 (UTC)[reply]

Relativity[edit]

I think that relativity began to appear in the calculations in 1984. — Preceding unsigned comment added by 86.151.50.217 (talk) 12:51, 4 May 2016 (UTC)[reply]

About 6 centimeters are involved, in the distance from the Earth to the Moon. — Preceding unsigned comment added by 86.151.50.217 (talk) 13:05, 4 May 2016 (UTC)[reply]

Long term accuracy[edit]

There should be a section on how far into the future and past lunar calculations be extended accurately, and how this has improved as lunar theory has been refined in recent years. I notice that the Celestial Mechanics page seems also to be uninformative on this important point. However some information can be found in List of future astronomical events.CharlesHBennett (talk) 08:36, 1 March 2020 (UTC)[reply]
