Tables of Ephemeris

Tables of Ephemeris are charts used in astronomy that provide the positions of celestial bodies—like planets, moons, and stars—at specific times. They serve as useful guides for astronomers, navigators, and stargazers, helping them predict where objects in the sky will be over days, months, or even years. By consulting these tables, one can determine when planets will be visible, understand their orbits, and plan observations or navigational routes. Essentially, they are a tool for understanding the movement of celestial objects in relation to Earth.
