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.
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.
Uranus.
When it is farthest from the Sun. This point is known as aphelion. *Aphelion = Furthest point from the Sun.
Mercury has the slowest revolution around the sun, taking about 88 Earth days to complete one orbit.
Pluto is the slowest planet to move around the sun, because of its far distance.
Mercury is the fastest moving planet around the sun. It is second slowest to rotate about its axis, Venus being the slowest.
Venus
Venus has the slowest rotational period- 243 days to rotate once.
Sedna.
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.
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.
Pluto
The Three-Toed Sloth
The Planet Venus has the slowest rotation rate because one day there is longer than the year on Venus or longer than its revolution around the 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.
