Among our sun's planets, Neptune enjoys that distinction. If we include dwarf planets, then Eris makes the longest journey (so far). We will likely discover icy bodies as big as Eris even further away.
Yes. The grater the distance, the longer an object takes to orbit.
Apsis
At its aphelionThe aphelion is the point in the orbit of a planet or comet that is at the greatest distance from the sun.
The point in a planet's orbit where it reaches its maximum distance from the Sun is called the Aphelion.
Neptune is the furthest planet from the sun, taking the longest time to complete one orbit, 164.79 years in total. Its distance means that is has further to go to complete one orbit, while it also means that the planet travels the slowest. The further a planet is from the gravitational pull of the sun, the slower it will move tangentially.

mercury. I think you mean "Orbit".
The planet's depends on the distance of the planet from the sun
The greatest difference in seasons will occur on a planet that has a circular orbit. This is because winds are created this way.
