- In Latin, the moon is known as "Luna", giving rise to the term "lunar", meaning "relating to the moon".
- In ancient Greece, the divine embodiment of the moon was named Selene. However, the goddesses Artemis and Hera were two other deities that were also associated with the moon.
- Selene was the sister of the sun-god Helios and the goddess of the dawn, Eos.
