Ursa Major
The North Star or Polaris in the constellation of Ursa Minor
So the earlier astronomers can locate things in the sky.. They used the constellations to help them point out certain things
"Canis Major" is the Latin name used for the constellation "the Greater Dog". The main stars have Greek letters in the Bayer system, combined with the constellation name. When naming a star in a constellation, the genitive (possessive) case of the Latin constellation name is used. For Canis Major that is "Canis Majoris". For example, Sirius is Alpha Canis Majoris in the Bayer star naming system. It means "Star A of the greater dog". (Sirius is also called the 'Dog Star'.)
the north star is what the 3 wise men used to find jesus
It is the brightest star in the northern part of the sky. It is part of the Little Dipper and the Big Dipper 'points' to it. The north star is on the tip of the 'Little Dippers' handle. The brighter 'Big Dipper' is easier to see in the night sky so that will be used as a reference point. The 'Big Dipper' constellation is composed of seven stars. Three form the handle and four form the spoon/dipper part. After finding the 'Big Dipper', trace an imaginary line from the two stars on the spoon/dipper opposite the handle. Follow the line to the brightest star; that's the North Star.

a large machine called the starlight navigator is used to procate where the particular star is and then its named after wherever it is eg north star 224.
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.
