All the planets and their moons do, but does the sun rotate?

yes.

an interesting fact from my astrophysics days is that the sun contains 97% of the solar system’s mass, but the rest (planets, asteroids etc) accounts for 97% of the angular momentum

of course it does.

Since the sun orbits the earth, it has to rotate otherwise how would the sun spots appear to move across the surface of the sun?

duh!

Everything’s rotating

I thought The Moon and Mercury were tidally locked and didn’t rotate around an axis (I assume that was the actual question).

But the Sun does rotate.

Stoner, how does the sun orbit the earth if the earth is flat then ?

The Moon does rotate, but appears to be in the same position to us as it rotates around the Earth.

relative to what?

All I know is that everything under the sun is in tune, but the sun is eclipsed by the moon.

Oh and there’s no dark side of the moon really.

As a matter of fact it’s all dark…….. bum bump bum bump bum bump……

Answer to OP, yes.

Supplementary question. If the earth is rotating at 500ish mph, and is going round the sun at ?mph, and the sun is rotating and moving around the galaxy, which is rotating and getting further away from other galaxies, how fast am I actually moving as I sit here typing this?

That’s easy – 50mph. But I have assumed an arbitary frame of reference for ease of calculation 😀

If the earth was rotating at 500mph ish then we’d have twice as long to spend on STW every day – basically we’d be doomed.

Our shift pattern rotates also and the plate in the microwave.

Should it be ‘The Sun’, as opposed to ‘the sun’?

Relative to what? You are not moving, and moving at the speed of light, and all the speeds between the two, depending on your frame of reference.

Mercury is not tidally locked after all.

In a sentence it is the Sun.

There is no (local) frame of reference in which you are moving at the speed of light.

But all other speeds in between, yes.

Don’t be ridiculous, everyone knows the Earth is banana shaped.

Another supplementary question: Do all microwaves rotate in the same direction?

Do all microwaves rotate in the same direction?

Only in the Southern Hemisphere.

Ooow, just found this thread, yummy….

sun makes one rotation in approx. 26(ish) days, which is it’s ‘Period'(T) Our period is 1 in 24 hrs.

Period of sun then, T = 1 x 24days, = 648hrs = 38880 mins = 2332800s.

We know that T= 1/freq (Hz), so Sun’s freq = 1/T, = 1/2332800s, = 4.3 x 10-7 Hz (slow).

Now, angular velocity omega (w)= 2xpixf. So for the sun,….

w = 2×3.14x(4.3×10^-7), from above, = 2.7×10-6 Hz….

Finally, w= v/r, r is sun’s radius = 6.96×10^8 m

v= wxr, = 2.7×10^-6 (Hz) x 6.96×10^8, = …….

188 (rounded up) meters per second.

So, when your looking (through correct glasses) at the sun imagine that a point on it’s equator is moving 170 times faster than a top sprinter (100m in 10seconds = 10ms)

Roughly speaking, 170 to 180 times faster than this guy

Roughly speaking, 170 to 180 times faster than this guy

But he is slower than a rhinoceros in a hurry. Four legs good…

Do all microwaves rotate in the same direction?

No ours changes direction every time you put it on. One time it will go clockwise the next anti-clockwise and so on.

HTH

Apparently this is because if all microwaves rotated the same way at the same time the earth would stop rotating.

If the sun is a fermion, then it must be only half spinning, no? 🙂

Damn it Jim! I’m a chemist, not a theoretical physicist!
