      One day in Neptune is about 16 hours. That means that the Ice Giant spins quicker than the Earth does. It is one of the planets with the shortest day lengths, next to Jupiter with about 10 hours and Saturn at 11 hours. 🙂

      Interesting fact: A moon of Neptune, called Triton, also shows its same face to its planet at all times. (Just like we always see the same side of our Moon from Earth.) This is called tidal locking. But if you were on the moon Triton around Neptune, a day there would correspond to almost 6 days on Earth.
