Earth revolves around the Sun and rotates on its own axis. Moon revolves around the Earth. Since Earth rotates on its axis from West to East, the sky appears to move from East to West. This can be seen easily with the movement of Sun and Moon across the sky during the span of hours. Similarly at night, stars move across the sky. Even though stars are very far away from us and they are not in moving around us, but due to the motion of Earth on its axis it seems that stars are moving around us.

Sky moves gradually over the night. If you are into sky gazing and enjoy looking at the stars, planets and Moon, you will notice slight movement of these objects with passing of hour. Often by using camera locked onto to a particular star, beautiful star trails are captured which so how the apparent movement of stars is a beautiful phenomenon.

Some move right while others move left. Now that we understand that stars move in the sky from East to West, you will find that when you are facing towards the North, the sky seems to move from your right hand side towards your left hand side. When you are facing the South, the sky seems to move from your left hand side towards your right hand side. This apparent movement becomes a great experience when you observe the stars from a vantage point high enough to get a good glimpse of horizon in all sides. You will feel as if there is a line passing through from the sky to your location and all stars North of it move in a certain direction and all stars South of it move in opposite direction.

South sky is light up in Surat. If you observe Scorpius constellation rise in the sky tonight from Western India, it will be coming up in the South-East sky and slowly move towards the West not rising high enough to reach overhead. While Virgo would be higher than Scorpius and too far ahead will be Leo. All this while you are facing the South. You will see many stars directly towards the South shining in groups. Hadar, Rigel and Regor are particular in this sky. Canopus is not visible in summer.

North star helps to determine the direction at night. Then if you look in the opposite direction towards the North, you will see Vega star coming up in the sky late into the night and the Ursa Major and Ursa Minor are going round about the Pole star. Venus is on the left hand side of you towards the west and it will go down the horizon.

More you look more you see. As you keep looking at the sky and your eyes get adjusted to darkness you will see more and more stars coming up like little bulbs of light
