If the sun is a star, how come it doesn't twinkle?

Answer 1

Stars often seem to twinkle because of our atmosphere distorting the light. The sun is to big to see this effect however the atmosphere still can cause the sun to look distorted, such as sunrise and sunset etc.

Answer 2

The twinkling is caused by the atmosphere. Stars are such a long way away that they are essentially point sources and so the atmosphere has to be very still for us to not see some disturbance along the line of sight. The Sun, the Moon and the planets have much larger angular sizes (though the outer planets Uranus and Neptune and the dwarf planet Pluto have much smaller angular sizes) and so the twinkling effect is averaged out. However when looking through a telescope the Moon and Jupiter can appear as though one is looking at them through a pool of water, the view rippling and shimmering due to atmospheric effects.

Answer 3

Star twinkling is an effect of atmosphere, not an inherent property of the star itself. It results from turbulence in the air refracting the light from the star. Stars (apart from the sun) are so far away that they appear to be points of light, so refraction will have a noticeable effect on how they appear. The sun is so close that it occupies a huge area of sky comparatively), so that the area over which the light appears to come is larger than the area over which the turbulence in the air has an effect.

That said, if you use an appropriate filter and look at the sun at times you can see a rippling effect, caused by the same turbulence that makes a star twinkle.

Answer 4

The stars you see twinkling at night occurs because of our atmosphere defracting the light.
If you were in space they would not twinkle.
The suns close proximity to us negates this effect

Answer 5

It is too close to the earth for that. 93 million miles

Answer 6

I guesse because we are to close to it for it to be affected by our atmosphere.
