Verified by Experts

In order to locate the Pole star in the sky, first of all Ursa Major or Big Dipper constellation must be located. The bowl of the Big Dipper consists of four bright stars

Consider two stars at the end of this bowl. Now, draw an imaginary straight line towards the Northern direction connecting these two stars

This imaginary line meets a star called the Pole Star. The length of the imaginary line from the bowl is about five times the distance between the two stars of the bowl.
