* Darkness: This is the most obvious thing - it's night! The sun's light can't reach this side of the planet.

* Cooler temperatures: The side of the Earth facing away from the sun experiences cooler temperatures because it's not receiving direct solar energy.

* Stars and constellations: Since the sun's light isn't blocking them, this is the side where you can see stars and constellations more clearly.

* The moon: While the moon is visible during the day, it's much easier to see it at night, especially when it's full.

* A different time zone: Depending on where you are on the Earth, the side facing away from the sun will experience a different time zone than the side facing the sun.
