Movement of stars with naked eye?

Is it possible to see stars' movement in detail with naked eye, without the help of any equipment? (telescopes, binoculars, etc) Considering the fact the closest star to earth is 4.24 light-years away. A light-year is 9.44 trillion km

Of course. You can see a shadow cast by the sun moving pretty easily.

You don't understand my point anon. Im not talking about the orbiting I was talking about the inner bodily movement of gases in the stars itself! I'm talking about the constant movement of the star within itself.

Then no.

Every star except the sun is just a point-source of light to the naked eye -- you can't see any detail at all.

And the sun is too bright to be observed directly with the naked eye.

Once while camping I looked up at the sky and when I focused my eyes on a particular star I could see it wiggling around. Apparently it's a well-known phenomenon and completely illusory.

Are you sure about it? The view at the sky from the north poles, wher sorrounding is darkest and the sky is brightest could make that visible?

You can't even see that for the sun much less other stars.

It's a problem of resolution not brightness your eye is physically too small to resolve the detail even if you could fix the heat haze from the earth's atmosphere.

So according to human eye, the sharpness of our vision is only for distance upto 20 feet. Above that its blurry but even seeing things which are above 3.097×10^16 feet, it could be possible to see stars in details imo. The sun is a different story because it's in the same solar system as us.

Turbulence in the atmosphere. Stars that are closer to the horizon twinkle more than stars at zenith since there is more atmosphere between you and the star.

this "sparkling" is caused by the Earth's atmosphere. It works like a lense.

The fastest star moves 10 arcseconds (1/360 degrees) across our view a year, so no
