you really do need to shave
If you count Pluto as a planet its Pluto :D
It is a Dwarf planet that has a retrograde axial spin or rotation. Clockwise from above its north pole.
Uranus spins on its side
Pluto has the longest REVOLUTION period Venus has the longest ROTATION period
The equatorial rotation velocity of dwarf planet Pluto is approximately 56 feet per second.
It takes Pluto 6.4 earth days to complete one rotation.
Neptune. It would be Pluto, but Pluto is a dwarf planet ( a planet that was a planet, but decided that it wasn't a planet)
Pluto was discovered in 1930 and assumed to be a planet at that time.
Venus
The size of planet Pluto is 1410 miles. But Pluto is now no longer a planet o body knows what actually happened at the precise time.
An hour is a period defined for Earth beings. However, an hour being a part of a rotation of a planet, based on Earths period of rotation, then an hour on Pluto would be:- R / 24 where R is the rotation period. Pluto =~ 6.4 Earth Days. So 6.4 / 24
Rotational period is the time it takes for a planet to make one full rotation around it's axis. Pluto takes about 153.3 hours to make one full rotation - or about 6.39 Earth days.
