Predicting Eclipses: How Astronomers Track the Shadows

Eclipses are predictable because the orbits of the Earth, Moon, and Sun follow precise patterns.
Ancient astronomers used the Saros cycle, about 18 years, to forecast eclipses.
The Babylonians were among the first to notice these repeating eclipse cycles.
Modern astronomy uses exact orbital mechanics and computers for precise predictions.
NASA can forecast eclipses centuries into the future with incredible accuracy.
Predictions include the type of eclipse (total, partial, annular, or lunar).
Maps show the path of totality for solar eclipses, often down to a few kilometers.
Predictions also give the exact timing and duration for any viewing location.
Understanding eclipse patterns helped refine knowledge of the Moon’s orbit.
From ancient cycles to supercomputers, predicting eclipses reveals the clockwork precision of the cosmos.
