Does the size of a planet affect its rotation?
The size and mass of a planet have nothing to do with their rotation speed or their orbital speed. Orbital speed is controlled solely by their mean distance from the sun.
Why do bigger planets spin faster?
But the four largest planets probably came together an entirely different way. That gas formed individual spinning disks (from which many satellites formed), and most likely it carried a lot of angular momentum as it fell onto the outer planets’ cores, causing them to spin faster and faster as they coalesced.
Is the rotation of a planet related to its distance from the Sun?
There is no direct relationship between the rotation of a planet (which governs day length) and a planets distance from the sun. The nature of the planets spin is more to do with the formation of the system early on, by large impacts of the more numerous bodies that would have been around.
How do you measure the distance between two planets?
There is a relationship between the planets distance from the sun and the time taken for one orbit (planets year), described in Keplers third law. The square root of the time taken to orbit the sun is proportional to the cube of the average distance between the sun. How do you measure the distance between two planets?
What’s the difference between the rotation period and the length of the day?
For planets which are even further out, the motion around the Sun is even smaller and the time required to compensate for it is only a few seconds. For Jupiter the difference between the rotation period and the length of the day is about 3 seconds; and for Saturn, Uranus and Neptune, the difference is about 1 second.
How is the Revolution of the Earth different from the rotation?
Rotation of the Earth is its turning on its axis. Revolution is the movement of the Earth around the Sun. The Earth takes 24 hours to complete a rotation with respect to the sun. The Earth takes a full year (365 days) for one complete revolution around the Sun.
