In last session, we saw that the stars, like the Sun, appear to move from east to west overnight. The sky we see at 9 pm is not the same as the sky we see at 4 am. Does the night sky change over the year? Do we see the same stars in January and in June? From your observation, you might know that the night sky looks different at different times of the year. Let us see why that happens.
