Question

what is constellation and give example and what is pole star?​

Answer 1

Usually they are said to represent an animal, mythological person or creature in a shape. When seen, the group of stars seem to make a pattern. The word constellation comes from Latin: con-, meaning together and stella- meaning stars. Some examples of constellations are Ursa major, Orion, Leo, Draco, Cancer etc.

POLE STAR

Polestar, also spelled pole star, also called (Northern Hemisphere) North Star, the brightest star that appears nearest to either celestial pole at any particular time. Owing to the precession of the equinoxes, the position of each pole describes a small circle in the sky over a period of 25,772 years.
