How are stars benificial to us?
stars are used for navigation...like polaris , ulsa minor and many others....
How far is polaris?
Polaris is approximately 430 light years from the Sun. Owing to its fortuitous position aligned with the north pole of the Earth, Polaris is commonly used for navigation; a sextant reading of Polaris can, with a very minor correction, be read as the latitude of a ship. However, Polaris is not especially bright; in fact, it is the dimmest star commonly used for celestial navigation. Each light year is about 9.5 x 1012 kilometers or 5.88 × 1012 miles
What is the significance of polaris in the sky?
It is almost directly above the North Pole and so was used, for centuries, for navigation.
Heavenly body used for navigation?
In addition to the Sun, Moon and Venus, there are 54 stars that were commonly used for celestial navigation (navigation by the stars). The most useful of these is Polaris, the North Star. Now, most navigation is done by electronic means such as GPS, Omega and LORAN.

Did the Polynesian navigators find their way by observing the star Polaris?
No. Polaris is only visible in the northern hemisphere, and the Polynesians did most of their navigation in the southern hemisphere, or so close to the equator that Polaris wouldn't be usable.
What type of light is the north star?
The North Star is a star named Polaris, in the constellation of Ursa Minor. It sits, entirely coincidentally, almost precisely above the North Pole of the Earth, and so it is very useful for navigation. Polaris is actually a pretty dim star; it is the dimmest of the stars generally used for navigation, solely because of its position in the sky. Metaphorically, the phrase "north star" is often used to denote a constant point of reference.

When was the star polaris discovered?
Polaris has been there all along. The ancient Phoenician and Chinese astronomers knew about it, and the Phoenicians used for navigation. (Not that it did them all that much good, since ancient ships were difficult to keep on track; the ships went where the wind did.)
Is Orion the constellation used for navigation?
