An Explanation for Planets Having the Same Direction of Rotation as Their Direction of Revolution ... If the planets and asteroids were formed from merely random accretions the would be an even mixture of the directions of revolution and rotation. The sun itself also rotates in a counterclockwise direction.

That is to say, the periods of rotation of the planets should be independent of their masses. At this point the question of what the rotation period does depend upon will be deferred. However let it be noted that the parameters ζ and γ depend upon the density of the planetary material from which the planets are formed.

Most planets' rotation is to the east, as for the Earth. Some planets (Venus, Uranus and Pluto) rotate to the west, if the North Pole is defined as the one 'on top' of the planet (above the plane of our orbit).

The Earth rotates around once in 24 hours - that's a rate of 1000 miles per hour!. The time it takes for the Earth to rotate completely around once is what we call a day. It's Earth's rotation that gives us night and day.

Constraining the Rotation Rate of Transiting Extrasolar Planets by Oblateness Measurements ... The solar system gas giant planets are oblate due to their rapid rotation. A measurement of the planet's projected oblateness would constrain the planet's rotational period. Planets that are synchronously rotating with their...

Q. Do all of the planets in the Solar System rotate? Do they all rotate in the same direction? Do they all wobble? Are the planes of their rotation all approximately parallel or do they just go in any and all directions?
