Astronomers have inferred that the Sun rotates by observing the motion of sunspots across its surface. This phenomenon, known as differential rotation, causes different parts of the Sun to move at different speeds, indicating that the Sun rotates. Additionally, observations of the Doppler shifts in the light emitted by different regions of the Sun also provide evidence of its rotation.

What has actually been seen by Astronomers?
A black hole, exoplanets. It has always been inferred.
Does the sun rotates to?
Yes, the sun rotates on its axis. It takes about 27 days for the sun to complete one full rotation.
What is the movements of the sun?
The sun rotates on its axis and revolves around the galactic centre.
What scientist studies the function of the sun?
Astronomers study celestial bodies, helio astronomers specifically study suns.
What causes the rising and the setting of the sun?
The rising and setting of the sun is caused by the Earth's rotation on its axis. As the Earth rotates, different parts of the planet are exposed to the Sun's light, creating daylight. When the part of the Earth you are on rotates away from the Sun, it appears to set.
How do astronomers know the sun's surface rotates at different speeds?
Sunspots rotate at different speeds.
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 has actually been seen by Astronomers?
A black hole, exoplanets. It has always been inferred.
Who is the Indian astronomers who discovered that the earth rotates about its axis daily?
aryabhatta
Does sun rotates arpund the sun?
If you mean whether the Sun rotates around an axis: yes, it does.
How do we known the sun rotates?
If sunspots are moving toward east, then sun rotates east
Does the sun rotates at the same rate that Earth rotates?
No.
Why is it that the sun rises when the sun rotates west to east?
The Sun appears to rise and set because the EARTH rotates; the Sun just stays where it is.
How do you now the sun rotates?
We know the Sun rotates because we can observe stationary sun spots moving across its surface.
Does the sun rotate at the same rate that the earth rotates?
No. The earth rotates once in about 24 hours. The sun rotates once in about 32 days.
How long do astronomers estimate the sun will last before it begins to die?
Astronomers think the sun will die in 2012
Does the sun rotates to?
Yes, the sun rotates on its axis. It takes about 27 days for the sun to complete one full rotation.
