Neptune is the furthest planet from the sun, taking the longest time to complete one orbit, 164.79 years in total. Its distance means that is has further to go to complete one orbit, while it also means that the planet travels the slowest. The further a planet is from the gravitational pull of the sun, the slower it will move tangentially.
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.
Planets travel slowest at their aphelion – the point in their orbit farthest from the sun. This is when they are moving at their slowest speed due to the effect of gravity.
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 the fastest moving planet around the sun. It is second slowest to rotate about its axis, Venus being the slowest.
As the planet approaches perihelion (point of nearest approach to the Sun), its orbital velocity gets faster, and it is fastest at perihelion. Similarly, at aphelion (point of furthest approach to the Sun), the orbital velocity is slowest.
The farther a planet is from the sun, the slower it moves in its orbit. So the planet with the largest orbit is the slowest. That's Pluto ... if you still consider Pluto a planet ... or Neptune if you don't.
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.
A planet moves slowest in its orbit when it is farthest away from the body it is orbiting, which is known as its aphelion. This is due to Kepler's second law of planetary motion, which states that a planet will move slower when it is farther from the body it orbits.
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.
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.
Planets travel slowest at their aphelion – the point in their orbit farthest from the sun. This is when they are moving at their slowest speed due to the effect of gravity.
Curiously, the nearer the planet is to the Sun the faster it orbits. Thus Mercury orbits the fastest, whereas Neptune is the slowest.
Mercury has the slowest revolution around the sun, taking about 88 Earth days to complete one orbit.
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.
Neptune. (Pluto is no longer considered a planet, but, rather, a dwarf planet.)
When it is farthest from the Sun. This point is known as aphelion. *Aphelion = Furthest point from the Sun.
The planet that has the slowest orbit would be Neptune due to the fact that is is furthest away from the sun. However, if you want to count dwarf planets, then Eris would be the slowest.
