Neptne takes 165 years.
Mars.
You might be thinking of Pluto, a dwarf planet, orbits the sun every 247.68 years. Pluto, however, is not a planet.
Mercury is the planet that orbits the sun every 165 days. It is the closest planet to the sun in our solar system and has the shortest orbital period.
Neptune orbits the sun roughly every 165 years.
Saturn
jupiter
Uranus
No planet in our solar system takes 88 years to orbit the Sun. Uranus orbits in 84 years and Mercury orbits in 88 days.
There isn't a planet that orbits the sun once every 4,000 years. However, in early 2014, scientists announced the discovery of dwarf planet 2012 VP113, which orbits our sun once every 4,000 years. Because of some anomalies in ts orbit, scientists think that there may be rocky planet 10 times the size of the Earth beyond 2012 VP113.
Mercury, is the smallest planet that orbits the sun.
Because as they revolve in their orbits around the sun, every planet averages a different distance from the sun, and that's how gravity works.
