Venus
Venus at 224 days.
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.
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.
Venus. it take 243 Earth days to rotate once
The order of the planets' rotation speeds from fastest to slowest is Jupiter, Saturn, Mars, Earth, Venus, Uranus, Neptune, and Mercury. This ranking is based on the time it takes for each planet to complete one rotation on its axis.
I believe the rotation of Venus is slowest, within our Solar System.
Sedna.
Venus rotates the slowest out of all the planets in our solar system. It has an extremely slow rotation, taking about 243 Earth days to complete one rotation on its axis.
The one that is farther from the sun... If Im not wrong. If so, I would want to now the right answer
You would think that the largest planet, Jupiter, would rotate the slowest (every 9 earth days and 15 minutes), but it is actually Venus that rotates the slowest at one rotation every 243 earth days.
Venus is the slowest planet with a rotational speed of 243 Earth days equaling one Venusian day.
Venus, it takes 243 Earth days to complete a single rotation. It also spins opposite most of the other planets in a retrograde motion (clockwise if you're staring down on it from the north pole). With as slowly as it spins usually it will complete a year in 224.7 Earth days before it spins a single time. This means that most places on Venus get sunlight for 116.75 Earth days. With the crushing atmosphere the light itself makes little difference though; even the night side has temperatures of over 800 degrees F.
