The suns rotation

[Bjarne]

Our sun rotates 1 times at 34.3 days
But it hasn’t always been so.

How much faster was our sun rotating for 1 -2 - 3 and 4 and 4.5 billion years ago

Hi there,

It is to simple to say that our sun rotates every 34.3 days. Our sun, unlike the Earth, does not rotates like a solid object. Therefore, the rotation period of the Sun is differential, meaning that different parts of the sun will take more or less time to complete a rotation.

This differential rotation of the Sun gives very peculiar effects, like the distortion of its magnetic field.

As fatra2 said, the sun is not a solid object. More like a rotating liquid. The equator rotates faster than the poles.

Yes right, (I know that), - this is not the question.
Let’s only speak about the rotation by the suns poles.
How much faster was the rotation of the sun for 4.5 billion years ago, and how much was it slowing down per 100 million years after it was created, - 500 million years after and 1+2+3+4 billion years after it was created...
