Before attempting the quiz, you may read an overview of the topic given below which will make you feel easier to answer the questions.
Overview:
All the stars that we see at night used to slowly shift from east to west because of earth's rotation around its axis. Because the Pole Star is directly situated over the earth's axis ( at the north pole) it remains fixed at a particular place. From time immemorial, the travellers and sailors have been using the Pole Star as their guide to determine the directions. People have also imagined different star groups
of recognisable shapes called constellations. We see different constellations at different times of the year because of the Earth's revolution around the Sun in space. Ancient people were able to tell the season and month of the year depending on the rising and setting of certain stars in the sky. Saptarshi or the Great Bear or the Big Dipper is a bright constellation in the northern skies looking like a question mark figure. We can join the two beginning stars of this question mark (called the Pointer Stars) figure and go along a straight line to meet the Pole Star. Other bright constellations of the night sky are Orion that looks like a hunter, Scorpios that looks like a scorpion and Cassiopeia that looks like a 'W' shaped figure. While stars twinkle, planets used to give a constant light because of their comparatively nearby distance from us. Also, while the stars remain fixed in the sky, the planets used to move in their background over time giving their name in Greek that means wanderers. We can see only five nearby planets in the sky with unaided eyes. It is highly dangerous to look at the Sun with a telescope without proper filters.
