Astronomers have inferred that the Sun rotates based on observations of its surface and magnetic field. By tracking the movement of sunspots across the Sun's surface, they have noted that these features take about 25 days to complete a rotation at the equator, while it takes longer near the poles. This differential rotation, combined with the Sun's magnetic activity, supports the understanding that the Sun is a rotating body. Additionally, the presence of solar storms and other phenomena is influenced by this rotation, further confirming the Sun's dynamic motion.
What else can I help you with?
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.
How do we known the sun rotates?
If sunspots are moving toward east, then sun rotates east
Why must astronomers say that the sun rotates once evert 27 to 31 days?
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 Why_do_astronomers_say_that_the_sun_rotates_once_every_27_to_31_days_rather_than_give_an_exact_number. One beltrotates every 27 days, another belt rotates every 31 days, and there are other beltsin between those that rotate at every rate in between 27 and 31 days. So there isn'ta 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 thatrotates exactly once in that period of time
How do we know sun rotates?
We know the Sun rotates because we can watch sunspots on the face of the Sun.
Did astronomers believe that the sun was part of earth?
No.
How have astronomers inferred that the sun rotates?
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.
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.
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.
