The Moon as an Astronomical Celestial Clock
Because the moon orbits Earth at approximately 0.55 degrees per hour, it serves as a natural astronomical clock against background stars.
Clearing Lunar Distances via Spherical Trigonometry
Clearing the lunar distance requires intricate spherical trigonometry corrections for atmospheric refraction and parallax offsets.
Nautical Almanac Ephemerides and Three-Hour Tables
Nautical almanac tables provided predicted distances for three-hour intervals, allowing captains to determine Greenwich time within 15 arcminutes.
