Pluto is the known planet with the longest period of revolution around the sun. Its 'year' ... the time it takes to make one full circuit in its orbit ... is 248 earth years.
Since it's discovery in 1930, Pluto has traveled less than 1/3rd of a full revolution around the sun.
It holds this record for 2 reasons:
1). Among all of the known planets, Pluto is farthest from the sun, so its orbit is the largest of all.
2). Its speed in orbit is the slowest of all the planets.
These factors are connected ... thanks to the way gravity operates, the farther any satellite is from the central body, the slower it moves in its orbit. Actualy, it would be Neptune, because Pluto is gennerally not a planet. It was classified as a Dwarf planet on October, 2008.
Neptune would move the slowest. The orbit speed is related to the distant the planets are to the sun. Farther the planet, slower the pace. Remember, Pluto is no longer a planet.
Mercury has the slowest orbital velocity around the sun compared to the other planets in our solar system. Its average orbital speed is about 47.87 km/s.
A satellite revolves around a planet as it orbits it in space.
When it is farthest from the Sun. This point is known as aphelion. *Aphelion = Furthest point from the Sun.
That would be the planet known as earth.it is our planet earth

Pluto is the slowest planet to move around the sun, because of its far distance.
Planets do not revolve around the Sun, they orbit. The planet which orbits slowest is Neptune at about 165 earth years per orbit [Pluto is a dwarf planet and orbits approximately once every 248 earth years].
Mercury is a planet. By definition, it revolves around the sun.
The speed of a planet revolving around the Sun is slowest at the aphelion, which is the point in its orbit farthest from the Sun.
Mercury is the fastest moving planet around the sun. It is second slowest to rotate about its axis, Venus being the slowest.
