Neptune has the slowest and longest orbit. It has a radius of 30 astronomical units (i.e. 30 times as far as the Earth), and it takes 165 years to go round once. So it has been round almost exactly once since it was discovered in 1846.
It was discovered officially on September 24 1846, and it completed its first revolution since discovery on June 30 2011.
What else can I help you with?
Which planet has the slowest orbit why?
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.
When is the speed of a planet revolving around the Sun be the slowest?
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.
What planet travels the slowest around earth?
There are no planets in orbit around the Earth !. Orbiting the Sun - Pluto has the longest orbital period at 248 years - although it has now been declassified as a planet. This leaves Neptune - with an orbital period of just under 165 years.
Which planet revolves very slowly around thesun?
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].
Planets travel slowest at the?
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.

Which planet revolves slowest around the earth?
Pre-Galileo, no planets revolve around earth
When is the speed of a planet revolving around the Sun be the slowest?
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.
What planet moves around sun the slowest?
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.
Slowest traveling planet?
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.
Which planet would orbit around the sun the slowest?
Neptune. (Pluto is no longer considered a planet, but, rather, a dwarf planet.)
What planet has the slowest revolution?
Mercury has the slowest revolution around the sun, taking about 88 Earth days to complete one orbit.
What are slowest to fastest planet to orbit the sun?
Curiously, the nearer the planet is to the Sun the faster it orbits. Thus Mercury orbits the fastest, whereas Neptune is the slowest.

When is the speed of a planet revolving around the sun the slowest?
When it is farthest from the Sun. This point is known as aphelion. *Aphelion = Furthest point from the Sun.
Which planet moves the slowest in its 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.
