lunar eclipse calculation

Lunar eclipse calculations involve understanding the positions and alignments of the Sun, Earth, and Moon. Astronomers use celestial mechanics and precise orbital data to determine when the Earth will cast its shadow on the Moon. By calculating the orbits and timings of these bodies, they can predict when the Moon will pass through Earth's shadow, causing a lunar eclipse. These calculations account for the Moon's orbit tilt, speed, and the Earth's size and shape, enabling accurate forecasting of eclipse dates, durations, and types (partial, total, or penumbral).
