What best explains why different planets have different year length
The length of a planet's year (one complete orbit around the Sun) is primarily determined by its distance from the Sun,
planets that are farther away travel in much larger orbits and move at slower speeds, leading to significantly longer years.
Neptune is much farther from the Sun than Earth. Explain how Neptune’s distance affects its revolution period and year length
Neptune is much farther from the Sun, so it travels a much larger orbit and moves more slowly in its orbit; this results in a much longer revolution period, giving Neptune a very long year

The planet with the shortest year ? Why - explain
Mercury , Because it is the closest planet to the Sun, it has the shortest orbital path and moves the fastest
This holds all the gases in a ball and keeps the planets in their orbit.
