Naiad is one of the moons of Neptune
The moon Naiad is named after the Naiads of Greek mythology. In Greek mythology, the Naiads were a type of nymphs who were associated with bodies of fresh water, such as springs, rivers, and fountains. They were believed to be the spirits or goddesses of these water sources. The naming of Naiad and other moons of Neptune follows a convention of naming them after characters from Greek and Roman mythology associated with the sea or water.
