Saros (astronomy): Difference between revisions

The '''saros''' ({{IPAc-en|audio=En-saros.oga|ˈ|s|ɛər|ɒ|s}}) is a period of exactly 223 [[synodic month]]s, approximately 6585.3211321 days, or 18 years, 10, 11, or 12 days (depending on the number of [[leap years]]), and 8 hours, that can be used to predict [[eclipse]]s of the [[solar eclipse|Sun]] and [[lunar eclipse|Moon]]. One saros period after an eclipse, the Sun, [[Earth]], and Moon return to approximately the same relative geometry, a near straight line, and a nearly identical eclipse will occur, in what is referred to as an [[eclipse cycle]]. A '''sar''' is one half of a saros.<ref>{{cite web
