SAROS
Saros
The saros is a period of 223 synodic months, that can be used to predict eclipses of the Sun and Moon. One saros after an eclipse, the Sun, Earth, and Moon return to approximately the same relative geometry, and a nearly identical eclipse will occur, in what is referred to as an eclipse cycle. A sar is one half of a saros.The above text is a snippet from Wikipedia: Saros (astronomy)
