Last year in January 2019, I viewed the total lunar eclipse in Cancer. Magazines like Sky & Telescope published detailed crater timings for observers using telescopes (like me). Such observations support the accuracy of the Moon's orbit calculated using gravity, Earth's penumbra and umbra size calculated based upon the geometry and distance of the Moon and its orbital velocity through Earth's shadow. While the ancients knew about the Saros cycle, ancients could never predict with such precision or accuracy solar and lunar eclipses like the modern, heliocentric solar system does using gravity, elliptical orbit of the Moon and rotating earth.
