Eclipse cycle - Wikipedia
WEBEclipse cycles have a period in which a certain number of synodic months closely equals an integer or half-integer number of draconic months: one such period after an eclipse, a syzygy (new moon or full moon) takes place again near a node of the Moon's orbit on the ecliptic, and an eclipse can occur again. However, the synodic and draconic ...
How Often Does a Solar Eclipse Happen? - timeanddate.com
WEBSolar eclipses occur in cycles, called eclipse cycles. One of the most popularly studied eclipse cycles is the Saros cycle , which the ancient Babylonians used to predict lunar eclipses. The Saros cycle is approximately 6,585.3 days, or around 18 years, 11 days, and 8 hours long, and it occurs due to a combination of three lunar cycles:
NASA - Eclipses and the Saros
WEBThe periodicity and recurrence of eclipses is governed by the Saros cycle, a period of approximately 6,585.3 days (18 years 11 days 8 hours). It was known to the Chaldeans as a period when lunar eclipses seem to repeat themselves, but the cycle is applicable to solar eclipses as well.
What is the Saros Cycle and How Does It Foretell Eclipses?
WEBJan 24, 2018 · Since successive eclipses in a saros cycle take place in different parts of the globe, how did the Babylonians, who didn't travel much beyond the region that is modern-day Iraq, discover the pattern? The answer is that saros cycles apply to lunar eclipses as well as solar eclipses — and a lunar eclipse can …
What are solar eclipses and how often do they occur?
WEBApr 8, 2024 · Eclipses only occur when the Sun lies at one node and the Moon is at either the same node or the one on the opposite side of Earth. If the Sun and the Moon are at the same node, we’ll experience...
Solar eclipse - Wikipedia
WEBA solar eclipse occurs when the Moon passes between Earth and the Sun, thereby obscuring the view of the Sun from a small part of Earth, totally or partially.
NASA - Periodicity of Solar Eclipses - NASA Eclipse Web Site
WEBAfter about 10 Saros cycles (~200 years), the first umbral/antumbral eclipse occurs near the South Pole of Earth. Over the course of the next 7 to 10 centuries, a central eclipse occurs every 18.031 years (= Saros), but will be displaced northward by about 250 km with respect to Earth's center.
Eclipse - Wikipedia
WEBAn eclipse cycle takes place when eclipses in a series are separated by a certain interval of time. This happens when the orbital motions of the bodies form repeating harmonic patterns.

WEBEclipses recur over the Saros cycle, a period of approximately 18 years 11 days. Each eclipse belongs to the Saros Series shown in column 4. The Eclipse Magnitude [3] gives the fraction of the Sun's diameter obscured at the instant of greatest eclipse (column 5).
Lunar Phases and Eclipses - NASA Science
WEBDuring a lunar eclipse, Earth comes between the Sun and the Moon, blocking the sunlight falling on the Moon. There are two kinds of lunar eclipses: A total lunar eclipse occurs when the Moon and Sun are on opposite sides of Earth. A partial lunar eclipse happens when only part of Earth's shadow covers the Moon.
