URANUS TAKES EIGHTY FOUR DAYS TO ROTATE
Mercury.
0.44401 days.
Venus.
It depends which planet you mean - the Earth takes 23 hours & 56 minutes to rotate once.
Mercury. It actually takes longer to rotate on its axis (89 days) than it takes to orbit the sun.
it takes 365 days for the earth to go around the sun once.
There is no planet that takes 25 days to rotate on its axis. However, the equator of the sun rotates in about 25 days. (Not all of the sun rotates at the same speed, it slows down as it gets closer to the poles. At the poles, the sun rotates in about 36 days, and in the middle it takes about 30 days.)
The fastest planet around the Sun is Mercury, which takes 88 days to orbit. The planet with the fastest rotation is Jupiter, which takes 10 hours to rotate.
Mercury is the closest planet to the sun thus Mercury has the shortest orbit duration. It takes the planet Mercury 88 days to rotate around the sun.
Neptune takes 16 hours 6 minutes and 36 seconds to rotate or spin once on its axis, or 0.67125 Earth days.
The planet Venus takes approximately 243 Earth days to complete one rotation on its axis. This is much longer than 28 days. The planet Mercury has a rotation period of about 59 Earth days, also longer than 28 days.
Mercury. Its takes around 58.65 days to rotate once on its axis relative to background stars.
