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 much later does the moon rise each night?
The moon rises about 50 minutes later each night, due to its orbit around Earth and the rotation of our planet.
What is the smallest planet's period of rotation?
The smallest planet, Mercury, has a period of rotation of about 59 Earth days. Its slow rotation speed means that a day on Mercury (from one sunrise to the next) is much longer compared to a day on Earth.
What planet takes 28 days to rotate?
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.
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.
How much light and warmth a planet receives depends on what?
The amount of light and warmth a planet receives depends on its distance from its star, the type of star it orbits, its atmosphere, and any greenhouse gases present. The planet's tilt and rotation also play a role in determining how much sunlight reaches different parts of the planet.
