Saros
A cycle of about 18 years 11 days and 8 hours, after which the Sun, Moon and lunar nodes return to almost the same arrangement — so an eclipse repeats, shifted about a third of the way around the world. Eclipses are grouped into numbered saros series that run for over a thousand years each, beginning as small partial eclipses near a pole and ending the same way at the other. Known to Babylonian astronomers, and the reason eclipses can be predicted centuries ahead.
