Celestial Navigation
Celestial navigation is the art and science of determining a vessel’s position on Earth using the positions of celestial bodies, such as the sun, moon, stars, and planets. It’s a technique that has been used for centuries by mariners to safely navigate the open seas.

- Star Positions: Stars have fixed positions on the celestial sphere and can be used as reference points for navigation.
- Timekeeping: Accurate timekeeping is crucial for celestial navigation to determine the precise positions of celestial bodies.
