Planet Neptune
Neptune.
Because Uranus' axis of rotation is in the plane of its orbit, the poles of the planet face the Sun. This means that each pole is illuminated for half of its 84.3 (Earth) year orbit, making a day on the planet last roughly 42 Earth years.
Neptune is the furthest planet from the sun, taking the longest time to complete one orbit, 164.79 years in total.
Since Pluto is now a dwarf planet, the last planet is now Neptune. The most recent planetary discovery occurred in 1930; the newly discovered body was named "Pluto". Since then, it has completed about 1/3rd of a revolution in its orbit around the sun. Nobody can say with certainty that Pluto is the 'last' planet, only that it is the one most recently discovered, the one at the largest known average distance from the sun, and the one with the longest known orbital period. So far....
uranus
A large orbit.
Unlike the Earth, however, the seasons of Neptune last for decades, not months. A single season on the planet, which takes almost 165 years to orbit the sun, can last more
Neptune is the last
Neptune.
Pluto's orbit is 248 years. Pluto has an elliptical orbit that takes it closer to the Sun than Neptune, for 20 years, out of its 248 year orbit of the Sun. So every 228 years, Pluto's orbit crosses Neptune's orbit. This last happened between 1979 and 1999.
because during its orbit pluto's orbit around the sun intercepts neptune which makes neptune either second to last or last

All planets are in their orbits
The planet with a summer that last for 21 years is Uranus. All of the seasons on the planet last for this amount of time.
Gravity and Enertia (Not that sure on the spelling of the last one)
Never. That's a fictitious planet that never really existed.
