PLUTO: Pluto is the farthest planet from the Sun, and has the longest orbit. On Pluto, a year lasts for 248.5 Earth years. Pluto's orbital path is unusual because it is elongated. When farthest from the Sun, it is about 4,500 million miles (7,400 million km) away - nearly 50 times farther away than Earth. Pluto is by far the smallest planet, and its moon is half its size. There may be other planets outside the orbit of Pluto, but they must be very far away, otherwise they would already have been found.
MERCURY: To put it simply, Mercury has an orbital period of 88 days (87.969 to be exact), which means a single year is 88 Earth days – or the equivalent of about 0.241 Earth years. But here’s the thing. Because 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.
