This varies, depending mainly on collisions that have occured in the past.
The rotation periods in days (time taken for the planet to rotate once on its axis relative to background stars) for each of the planets is as follows;
Mercury = 58.646
Venus = -243.019 (spins in opposite direction)
Earth = 0.997
Mars = 1.026
Jupiter = 0.410
Saturn = 0.426
Uranus = -0.718 (spins in opposite direction)
Neptune = 0.671
This is different to an `apparent day` as an `apparent day` factors in the movement of the planet around the sun during its rotation.
negative results for Venus and Uranus show that these planets spin in the opposite direction to most other planets (retrograde).

How long does it takes the earth to rotate on its axis?
The period is 24 hours, governed by the Sun rising and setting. But this is a trick question because during that 24 hours, the Earth has gone round its orbit a little so it has to rotate for four extra minutes each day to get to noon with the Sun at the same place in the sky. The period relative to the stars is 23 hours 56 minutes, so our 24-hour day makes all the stars rise and set four minutes earlier each day.
If a planet orbits the sun but does not rotate on its axis at all how long would a day be on that planet?
That depends on what you're asking. If it has no rotation, as in, it faces a fixed point in space, the day and night would each be half the length of its orbital period, or year. For the Earth, that would be 6 months. However, that is pretty much impossible. What normally happens is that for various reasons, planetary rotation slows until one face remains tidally locked toward the star. In that case, one side has perpetual day, the other perpetual night. There's also a 3:2 resonance where the planet appears to rotate backward, like Venus.
What is your Mass on each planet?
Your mass does not change no matter which planet you're on. That is because mass is a measure for how much material there is. However, your weight will change because it is the measure of how much you're being pulled down by a planet.
How much time does it take for the moon to make one rotation?
The rotation period of the moon is 27.32 days.
Do all planets rotate on their axes at the same rate?
No. Each planet spins at a rate determined by its mass and interactions with the gravity of the Sun and the other planets. This rotational speed may have changed considerably since the planet formed. The large gas giants (Jupiter, Saturn, Uranus, and Neptune) spin much faster than Earth, at least as far as can be determined from their exterior cloud layers. Saturn, especially, has a faster rotation speed at its equator than at its poles.
Difference between mercury and Earth's rotation?
Nothing, except the speed of the rotation and how much the planet is tilted on its axis.
Which Planet has shorter rotation time Earth or Mars?
Earth, but there's not much difference.
How much water is there on each planet?
we dont know
How is Uranu's rotation different from the rest of the outer planet?
Uranus has a different rotation around its axis because it is tilted at an angle. I hope this helps! The angle is much bigger at about 98 degrees. That's the difference. The angle of tilt is away from the perpendicular to the planet's orbital plane, of course.
How much is a 1575 degree rotation?
Answer: 130 degrees. 360x4=1440 degrees. So each time we have 360 degree rotation, we end up where we started. The rotation will be 1575-1440=130 degrees.

Why did neptune become the farthest planet from 1979 to 1999?
Plutos orbit is highly eccentric - during one rotation of the sun its distance from the sun can vary considerably. For 20 years of each of its orbit - a small fraction, it is closer to the sun than Neptune, which has much more of a regular orbit. Neptune is now the furthest planet again as of 2006. This time its for another reason - Pluto is no longer classed as a planet, but is instead a Dwarf Planet.
What planet is similar to Venus?
In many ways we are (Earth). Mass and size, and thus gravity is close. But Venus has no moon, a very slow rotation, and an atmosphere that makes ours look puny. And that slow rotation means not much of a magnetic field.
How much time does Saturn take to complete one full rotation?
The sidereal rotation period of Saturn (the time between a point on the planet facing a certain distant reference point) is 10 hours, 32 minutes and 35 seconds.
What happens to a gaseous planet when it rotates faster?
A planets rotation speed stays pretty much as it is. A faster rotating gas planet (or any planet for that matter) will become squashed or flattened (an oblate spheroid). So the diameter accross the equator will be bigger than the pole to pole diameter.
How much time each planet takes to revolve around the sun?
365 days
How is the rotation of Uranus different from the rest of the planets?
Uranus has a different rotation around its axis because it is tilted at an angle. I hope this helps! The angle is much bigger at about 98 degrees. That's the difference. The angle of tilt is away from the perpendicular to the planet's orbital plane, of course.
