What is the Moon's Latin name?

The Moon’s Latin name is Luna.

The word comes from Latin lūna, the ordinary Roman term for the Moon and also the name of its divine personification. English scientific words such as “lunar” descend from this Latin root. In astronomy and science fiction, Luna is sometimes used to distinguish Earth’s Moon from the many other moons in the Solar System.

Luna is not the only traditional name. The ancient Greeks called the Moon Selene, while English “Moon” developed from Old English mōna. A common mix-up is treating Luna as a modern nickname rather than a Latin name; it is the classical Latin word itself. “Solar,” by contrast, relates to Sol, the Sun—not the Moon.
