Who is the goddess of the moon in Greek mythology?

Selene is the goddess of the moon in Greek mythology. She is often depicted as a beautiful woman driving a chariot across the night sky, illuminating the darkness with her silvery light. Selene represents the full moon and is associated with the lunar cycle, embodying the ethereal and gentle qualities typically attributed to the moon.

While Artemis, her twin sister, is also connected to the moon and often associated with the hunt and the wilderness, Selene specifically personifies the moon itself. Aphrodite represents love and beauty, and Demeter is the goddess of agriculture and the harvest, neither of which are related to the lunar aspects that Selene embodies. Hence, Selene is the correct answer in this context.
