(a) direction facing the polestar
(b) direction opposite to the polestar
(c) direction keeping the polestar to his left
(d) direction keeping the polestar to his right
Answer: (c)
Polaris, commonly known as the North Star, is the closest relatively bright star to the north celestial pole. Polaris is easily visible to the naked eye, but not exceptionally bright. It is the brightest star in the constellation Ursa Minor, but only the 48th brightest star in the sky. This, however, does not mean that it is not particularly luminous. As a yellow supergiant, the star is immense and only appears faint because it is so distant from Earth.
Option (c) is correct: In ancient times, people used to determine directions during the night with the help of stars. The North Star indicates the north direction. It is also called the Pole State. It always remains in the same position in the sky. The Pole Star is situated in the direction of the earth’s axis. It is not visible from the southern hemisphere. The convenient way now to reach his village is to walk in the direction keeping the pole star to his left.
