Venus is known for having a day longer than its year. A day on Venus, defined as one full rotation on its axis, takes about 243 Earth days, while it only takes about 225 Earth days to complete a rotation around the Sun. This unique situation is primarily due to its slow rotation speed and retrograde rotation, meaning it spins in the opposite direction to most planets in our solar system. As a result, one day-night cycle on Venus exceeds its orbital period, highlighting the intriguing and unusual characteristics of this planet.
