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.
Moldova has the slowest rate of urbanization.
The velocity of a planet around the sun is inversely related to the distance from the sun. So the slowest planets are the ones farthest out. If you consider Pluto a planet, it takes the longest time to revolve around the sun. If you do not consider Pluto a planet, then Neptune would be the farthest planet from the sun and takes the longest time to revolve around the sun.
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.
rate of absorption from fastest to 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.
