Navigation Act
The North Star, also known as Polaris, is significant in navigation and astronomy because it remains nearly fixed in the sky, making it a reliable reference point for determining direction. Sailors and travelers have used the North Star for centuries to find their way, as it always points towards the North Pole. In astronomy, the North Star's position can help locate other stars and constellations in the night sky.

Entirely predictable. It's so predictable that we can measure the position of the Sun in the sky to determine our position, a method we call "celestial navigation".
The line where the earth and sky seem to meet is called the horizon. It appears as a visual boundary separating the land from the sky. The horizon is an important reference point for navigation and observing celestial events.
In the Odyssey, the Pleiads are a group of seven sisters who appear in the night sky. Boötes is a constellation mentioned in the Odyssey as guiding the sailors. The Bear is likely a reference to Ursa Major, another constellation used for navigation.
Yes, Orion is a prominent constellation used for navigation because its position in the sky remains relatively fixed and it is visible from both hemispheres. The three stars in Orion's belt are particularly useful as they point towards other important stars and constellations.
I insist you buy a GPS navigation system , this website does not hold all answers , i hope you will follow
The sun, moon, and stars have traditionally been used as heavenly bodies for navigation. Sailors and travelers have relied on their positions in the sky to determine direction and time, guiding their journeys across land and sea.
Sailors in the southern hemisphere use the Southern Cross constellation to aid in navigation. By identifying this prominent star pattern, they can determine their heading and approximate their position in the night sky.
