A planet's year is the time it takes to complete an orbit around the sun. So the planets with the longest years are the ones farthest from the sun. Pluto has the longest in our solar system, followed by Neptune, then Uranus, Saturn, Jupiter, and so on.
The order of the planets by longest year is the normal order (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune). The farther away a planet's orbit is from the Sun, the longer the year.
(The year is proportional to the distance to the power 1.5) In our solar system, Mercury has the shortest year. Neptune has the longest.
Mercury has the longest year in revolution among the inner planets, taking about 88 Earth days to complete one orbit around the Sun.
Mercury has the longest cycle of day and night among the terrestrial planets. A day on Mercury lasts about 176 Earth days, which is longer than a year on Mercury. This is because Mercury rotates very slowly on its axis.

No, a planetary nebula is not surrounded by planets. It is an expanding shell of glowing gas ejected by a dying star, which is usually located in the center. The term "planetary" is a historical misnomer as these nebulae have nothing to do with planets.

In Sol, that would be Uranus. If you include dwarf planets, Eris.
The adjective form of "planet" is "planetary." It describes anything related to or characteristic of planets, such as planetary systems, planetary atmospheres, or planetary science.
Planetary science (and rarely, planetology) is the name given to the scientific discipline of the study of planets. This subdivides into more specific disciplines, including planetary astronomy, planetary geology, and geophysics.
In Planetary Science the two largest planets are Jupiter and Saturn.
Planets orbit in an ellipse.
A planetary geologist studies rocks on other planets. They analyze the composition, structure, and history of rocks to understand the geology of other planets in our solar system.
They could either be a planetologist, a planetary scientist, or planetary astronomer.
