In the northern hemisphere, the North Star (Polaris) is constant. Other stars are known to rise and fall at certain times of the year.
It is my understanding that the Southern Cross is a constant constellation (non-moving) in the Southern Hemisphere, but I do not know that to be a fact.

Zero was not in use in ancient times. It was not introduced into Europe until the 12th century and then it came from Arabia.
The nautical star is a very old modern tattoo, going back at least a century or more. Back in the days of yore, before modern navigation, sailors would navigate in part by the stars in the night skies, in particular the North Star in the Northern Hemisphere, and various other constellations of stars in the night sky. In the Southern Hemisphere, sailors had to use different stars and the Southern Cross became quite well-known. Sailors would then tattoo nautical stars on them because they relied on the stars to take them home, and being superstitious, they hoped their star tattoos would get them home safely as well. Compass stars are also popular for this reason. The nautical stars were originally used by sailors to help guide their way as they sailed through the night. They relied upon the stars to protect them and bring them home safely. A lot of soldiers get nautical stars for the same reason...protection. It is a symbol of protection and guidance. It was a very popular tattoo among sailors. So a case could be made that the nautical star tattoo, or a tattoo of any star for that matter, would be a symbol of guidance. Now as time has passed the nautical stars represent the direction of one's life, for those of us who are not sailors but still need guidance. Some say that if the nautical star is pointed upwards they have a higher outlook on life and so on. The meaning of the Nautical star is to create your own path, but use the stars as a guide when you are lost or scared.
Astrolabes had numerous purposes. At sea, the astrolabe would have been used to calculate one's position in the water based on the position of the sun, stars, or the moon.
Ancient sailors used the stars to navigate between ports.
* The presence of seabirds would indicate the location and distance of land masses.* It is known ancient sailors were able to navigate by the use of stars.* Early mariners may have known that ocean currents vary during different times of the year.
Well, on MY planet, there is only one moon. Not sure about your planet. Here the sailors generally do not navigate by the moon- but they do use stars. In the north, sailors use the Pole Star, also called the North Star or Polaris. In the far south, you can't see Polaris, so sailors use other groups of stars, like the Southern Cross.
Sailors in the roman time used the north star for their navigation.
The invention that helped sailors steer without seeing the sun or stars is the compass. Compasses use the Earth's magnetic field to show sailors which direction they are heading, helping them navigate even when visibility is poor.
Because stars not like planets revolve and stars last at the night sky for many many years even at your lifetime.
high magnetic power which enable it to use in compass
The sailors used the positions of celestial bodies, such as the sun, moon, and stars, as a frame of reference for navigation at sea. By tracking these celestial bodies, sailors could determine their position and navigate their ships accordingly.
They used them to help them find their direction.
People use the stars for navigation, to track time, for storytelling and mythology, and for inspiration and wonder. Throughout history, stars have played a significant role in shaping various cultures' beliefs, science, and art.
It is called "Celestial Navigation", and was a method of finding your way from Point A to Point B across the vast and featureless ocean by using positions of known stars.
