When you are unable to see some stars in winter that you saw in summer, you are witnessing Earth’s revolution movement.
The earth revolution is the movement of the earth known as orbital motion around the sun. According to scientists, our planet earth revolves around the Sun, producing the 365-day year.
However, the earth revolution movement has many effects, one of which is that it caused us to be unable to see some stars in winter that we normally see in summer. This is because as the earth revolves around the sun, we observe some stars have disappeared from our view while others become visible at night which weren't visible during some certain period of the year.
Hence, when you are unable to see some stars in winter that you saw in summer, you are witnessing Earth’s revolution movement.
