Question

The Pole star can be located with the help of
(A) Ursa Major
(B) Big Dipper
(C) Saptarishi
(D) All of the above

Answer 1

Hint: The polar star is the largest of all the stars and will be the first star to rise in the sky after sunset. It rises in the north and is thus used as an indicator to find directions.

Complete Step-by-Step solution
The constellation of Ursa Major is in the northern sky. Its name means "great bear" or "larger bear" in Latin. The smallest bear is represented by Ursa Minor. Its brightest stars form the Big Dipper asterisk, one of the most recognizable forms in the sky, also known as the Plough. The ancient Greeks identified Ursa Major as a bear, whose name is Latin for the 'greater bear.
We can find the pole star from Ursa Major by following the below mentioned steps:
-Locate the Ursa Major and find the quadrilateral in it.
-Choose the two stars on the far side of the quadrilateral.
-Join these stars with a line and extend this imaginary line to the top of the ladle.
-The faint star that meets this line is the star of the pole.
-The Ursa Major is also known as Big Dipper. In India, the Big Dipper or the Ursa Major is known by the Hindi name “Saptarishi”.
Hence, the position of the pole star can be easily located by the help of Ursa Major or the Big Dipper or the Saptarishi.
So, the correct option is (D).

Note
As in the Indian mythology, the pole star is called the Dhruv star, honoured by Lord Vishnu, to be the very first ever star in the sky. When people did not have any device like compass they used the polar star as a reference to the north.
