Saros 126 contains 72 events, including the 2026 eclipse near the Perseid peak.
A Saros series is a sequence of eclipses produced by repeating orbital geometry. The 2026 eclipse is identified as event 48 of 72 in Saros 126, placing it well within the series rather than at its beginning or end.
The series began with a partial solar eclipse in 1179. Its eclipses changed type over time, progressing through partial, annular, hybrid, and total phases before eventually returning to partial eclipses.
The Perseid shower is not part of the Saros cycle. It repeats annually because Earth crosses the debris stream of Comet Swift–Tuttle, whereas Saros numbering tracks eclipse alignments involving the Sun, Moon, and Earth.
