The orbit of the Moon

According to Gutzwiller, “understanding the motions of the Moon is possibly the first problem that excited the scientific curiosity of humankind”. In fact, the attempts to make reliable and accurate ephemerides for the Moon were a key factor in the initial developments of exact sciences. I will briefly recall the main players in the early development of lunar theory, and will describe some recent results concerning periodic orbits in the lunar problem.
