A day on Venus is longer than its year.

Venus rotates on its axis extremely slowly, taking about 243 Earth days to complete a single spin. It orbits the Sun much faster, completing a full revolution in about 225 Earth days. That means one Venusian day — a full rotation — is actually longer than one Venusian year.

To make things stranger, Venus spins in the opposite direction to most planets in the solar system, a trait called retrograde rotation. Because of how that rotation interacts with its orbit, a full solar day on Venus — sunrise to sunrise — works out to roughly 117 Earth days, still far longer than a day on Earth, though shorter than the planet’s own rotation period.
