Well, I live on Neptune, so our year is like 165 Earth years. I'll never have a birthday. -.-
Neptune is much further from the Sun, so its path is a lot longer and so it takes more time.
The farthest planet from the sun used to be Pluto. Pluto is now considered to be a dwarf planet, not a planet. When Pluto was a planet, its orbit would sometimes take it closer to the sun than Neptune, making the Neptune the farthest planet from the sun for that period of time.
