why do some stars seem to twinkle faster than other stars?

Answer 1

the twinkling of a star is due to the atmospheric refraction of starlight.Star light travels from rarer to denser medium (hot to cold) so the atmosphere bends the star light towards the normal.That's why it appears slightly higher than the actual position of star when viewed from the horizon.
But the apparent position of the star doesn't remain stationary as the physical conditions of the atmosphere is always changing.Therefore the apparent position of the star fluctuates and the path of rays commin from the star goes on varying slightly.Thus the star light entering the eye fluctuates (increase or decree_ randomly with time.Due to the light flux entering the eye the star appears brighter sometime, fainter.Thus the fluctuating apparent position of the star gives rise to the twinkling of starts.
now u may ask why plants dont twinkle..its box they are not very distant as the stars.Stars can be considered as a point source of light where as the plants can be considered as many source of light such that they nullify the twinkling effect,Hence, turbulent atmosphere is unable to cause sufficient variations of star light entering our eye.

Answer 2

Stars twinkle due to impurities in our atmosphere such as dust, as well as visibility distortions such as diffraction due to temperature differences. Because of this, the two major factors that affect a given star's "twinkle rate" are the amount of interfering atmosphere and the visible size of the star.

When a star is closer to the horizon, its light must pass through much more of the Earth's atmosphere. This will allow a greater amount of impurities and distortions to interfere, causing it mostly to become dimmer, but also cause a faster, more sporadic twinkling. This has nothing to do with the star's distance from the Earth, only its orientation within the night sky.

If a star is visibly smaller (its apparent size as viewed from Earth, not its actual size), then it can be more easily affected by smaller impurities in the atmosphere, and affected more strongly by any atmospheric phenomena.

Answer 3

Heat vibrations in earth's atmosphere cause the twinkling of all the stars, especially those which are near the horizon. Then the travel through the air is longer.

Answer 4

some stars twinkle very fast because of the enormous amount of heat present in them.The greater the amount of heat the faster the twinkle.

Answer 5

Stars twinkle in general because of the gasses in our own atmosphere.

Answer 6

because,the new born star likes to twinkle more than the other one

Answer 7

hi ravi
the distant a star is, the more it twinkles ,since light from distant stars twinkle more due to more atmospheric refraction

Answer 8

the stars which are farther away from rhe earth twinkle faster!

Answer 9

because they are twinkle twinkle little stars

Answer 10

I think its bcoz of the distance factor. Some stars are nearer than the others. That might b the reason.
