In Rome, Zeus was called Jupiter. He controlled the sky, the moon, and the weather: wind, rain, and thunder. Today, we call one of the planets in our solar system Jupiter, after the Roman name of the king of the gods. The planet Mars is also named after a Roman god—the god of war. And do you remember the god of the sea, Poseidon, who tried to keep Odysseus from getting home? The Romans called this sea god Neptune. Our solar system also has a planet named Neptune.
