What are the 12 main Greek gods?

The 12 Olympians are the central deities of the Greek pantheon, and they traditionally live on Mount Olympus. The standard list includes Zeus, Hera, Poseidon, Demeter, Athena, Apollo, Artemis, Ares, Aphrodite, Hephaestus, and Hermes — with the twelfth spot alternating between Hestia and Dionysus (Wikipedia (reference for Greek deities)). The term Olympian itself comes from Mount Olympus, the mythical home of these gods (Grand Valley State University (academic teaching resource)).
