Different parts of the Sun rotate at different speeds, which is how we know that the Sun isn't a solid. The equatorial regions of the Sun rotate in about 27 days, but the polar regions take a little longer; about 33 days.

Is the sun rotating?

yes it is it takes 27 days for it to rotate>.


Why do astronomers say that the sun rotates once every 27 to 31 days rather that give an exact number?

In this case, "27 to 31 days" doesn't mean a wishy washy, inexact number. Since the sun isn't solid, there's no reason that all of it has to rotate at the same rate, and in fact it doesn't. Different "latitudes" on the sun rotate at different rates. One belt rotates every 27 days, another belt rotates every 31 days, and there are other belts in between those that rotate at every rate in between 27 and 31 days. So there isn't a single "exact number" for the sun, as there is for every solid body including the earth. For any rate you want to name between 27 and 31 days, there's a part of the sun that rotates exactly once in that period of time.

How many times does the sun rotate per hour?

0.345, it takes the sun 27 days to rotate on its axis once.


Does the sun have a revolution?

Yes. The Sun rotates every 25.5 days at the equator. Because the Sun is not solid, various regions rotate at different speeds. The polar regions rotate every 36 days, and in-between latitudes spin at in-between speeds.


How often does the sun rotate on its axis?

The sun rotates on its axis approximately once every 27 days. This rotation period can vary slightly due to the sun's differential rotation, where different parts of the sun rotate at different speeds.


How many days in one year on the sun?

There are not days on the Sun as we experience on Earth. The Sun does rotate on its axis, but it takes about 27 Earth days for one complete rotation.


Why do astronomers say the sun rotates every 27 to 31 days rather than give an exact number?

The sun is not a solid object and different parts of it rotate at different speeds.


What is the revolution of sun in years?

The sun rotates around it's own axis every 27 days. Interestingly, the sun's outer layer (a gas) rotates once every 35 days. If you were asking how long it takes for the sun to rotate around the galaxy (a cosmic year), estimates vary between 225 and 250 million years.


What is the rotational speed of sun?

The Sun is not solid; it is a ball of highly compressed plasma, which behaves like a little like a liquid. The polar areas of the Sun rotate in about 33 days, while the equatorial areas spin more quickly, in about 28 days.
