WebAs seen from Earth’s surface, Mercury hides in dusk and twilight, never getting more than about 28° in angular distance from the Sun. It takes about 116 days for successive elongations —i.e., for Mercury to return to the same point relative to the Sun—in the morning or evening sky. This is called Mercury’s synodic period. WebBecause of Mercury’s slow rotation (once every 58.646 days) and its rapid orbital speed (47.362 km/s), one day on Mercury actually works out to 175.96 Earth days. A Year on Venus The second closest planet to our Sun, Venus completes a single orbit once ever 224.7 days. This means that a single year on Venus works out to about 0.6152 Earth years.
