Ok so we revolve around the sun. At nighttime in January we face away from the sun to see the nighttime sky and stars.
6 months later in July we’re on the opposite side of the sun and now again at nighttime we face away from the sun.
But this direction is now 180 degrees away from the January direction… but the nighttime sky is still the same
How is that possible
The night time sky is not the same as the constellations above you will look different. It’s difficult to tell, especially if you live somewhere with a lot of light pollution, but the night sky does change. If you are near some place rural where the sky is clear, check it out! It’s pretty neat. Hell, the ancient peoples (Greeks, Chinese, Romans, etc.) wrote mythos relating to how the constellations, perceived as gods, appear and disappear depending on the season.
Fun fact, there are some constellations that are never visible to those in the northern and southern hemispheres, especially when you go near the poles.
