Solution

(a) A group of stars forming a definite shape is known as constellation. Few examples of constellations are Orion, Big Dipper.

(b) The points to be considered before doing skywatch are:

The place chosen for skywatching should as far as possible from the city.

The night chosen for skywatching should be new moon night.

Binoculars or telescopes should be used for skywatching.

Pole Star should be chosen as a reference point for skywatching.

Skywatching should begin with stars in west.

(c) Yes, it would certainly be wrong to say that planets, stars and nakshatras affect human life. This is because till now there is no credible evidence supporting astrology. Science, as we know, does not follow beliefs but has its basis on observations and evidences. Thus, it has rejected the thoughts and beliefs of many that the planets, stars and nakshatras affect human life .
