The moon is also called LUNA by the greeks just kidding thats not true that it was by the greeks:)
The Romans referred to the moon as Luna. The Greeks called it Selene. Both names were the names of their respective lunar Goddesses.
When the ancient Greeks looked at the moon they say Selene the goddess of the moon.
Artemis
The Ancient Greeks were the first to view the moon.
The Greeks god of the sun was Apollo and that was the name given to the US space program that landed men on the moon.
Selene
The Romans named the Greeks in Greece.
Greeks
Apollo is the greek god of the sun. He drove a sun chariot above the earths atmosphere that the greeks associate with the sun, so it would be appropiate to name it Apollo as the spaceship went outside the atmosphere to the moon, as the greeks believed apollo did with the sun
Selini (pronounced: ''Seleeni''), or fegari.
The ancient Greeks had three Goddesses of the Moon, Artemis - Waxing Moon, Selene - the Full Moon and Hecate - the Waning Moon.
