At the "aphelion".
The farthest one is the slowest - Neptune
Venus is the slowest planet with a rotational speed of 243 Earth days equaling one Venusian day.
The orbital speed of a planet is fastest when it is nearest the Sun.

The speed of planets will vary as they travel at different speeds. Mercury is the fastest planet while Pluto is the slowest. The speed of the planets is influenced by how close they are to the sun.
When it is farthest from the Sun. This point is known as aphelion. *Aphelion = Furthest point from the Sun.
Pluto is the slowest planet to move around the sun, because of its far distance.
Sedna.
The farthest one is the slowest - Neptune
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.
Venus is the slowest planet with a rotational speed of 243 Earth days equaling one Venusian day.
Mercury is the fastest revolving planet. The speed of a particular planet depends on its revolution around the sun as well as its rotation on its own axis. The fastest planet of the solar system with reference to revolution is Mercury. On the other hand, the fastest planet with reference to rotation is Jupiter.
If you still consider Pluto to be a planet then Pluto would be the slowest to orbit the sun. If you don't believe Pluto is a planet anymore then Neptune would be the slowest planet to orbit our sun.
It increases in order to conserve angular momentum.
Venus is the slowest planet with a rotational speed of 243 Earth days equaling one Venusian day.
The orbital speed of a planet is fastest when it is nearest the Sun.
Orbital speed is determined by the mass of the body and the distance from the sun. Given its extreme distance, Pluto has the slowest orbit. However, Pluto is no longer considered a planet, but instead a planetoid. Therefore Neptune now has the slowest orbit.
