They wouldn't sprinckle, but they appear to twinkle.
This is because of dust in the atmosphere that block the light from the starts before they reach are very eyes.

Ever notice how a coin at the bottom of a swimming pool seems to wobble from side to side? This phenomenon occurs because the water in the pool bends the path of light from the coin. Similarly, stars twinkle because their light has to pass through several miles of Earth's atmosphere before it reaches the eye of an observer. It is as if we are looking up at the universe from the bottom of a swimming pool. Our atmosphere is very turbulent, with streams and eddies forming, churning around and dispersing all the time. These disturbances act like lenses and prisms that shift the incoming light from a star from side to side by minute amounts several times a second. For large objects like the moon, these deviations average out. Stars, in contrast, are so far away that they effectively act as point sources, and the light we see flickers in intensity as the incoming beams bend rapidly from side to side.

Twinkling is caused by variations in density of the atmosphere distorting the light - think of high and low pressure centers but in layers between the viewer and the star. The less variation in the atmosphere, the less twinkling and none with a vacuum as in outer space. On a hot turbulant night there is lots of twinkling as the air moves.

you mean twinkle??..
no they dont..
The scientific name for the twinkling of stars is stellar scintillation (or astronomical scintillation). Stars twinkle when we see them from the Earth's surface because we are viewing them through thick layers of turbulent (moving) air in the Earth's atmosphere.
Stars (except for the Sun) appear as tiny dots in the sky; as their light travels through the many layers of the Earth's atmosphere, the light of the star is bent (refracted) many times and in random directions (light is bent when it hits a change in density - like a pocket of cold air or hot air). This random refraction results in the star winking out (it looks as though the star moves a bit, and our eye interprets this as twinkling).
Stars closer to the horizon appear to twinkle more than stars that are overhead - this is because the light of stars near the horizon has to travel through more air than the light of stars overhead and so is subject to more refraction. Also, planets do not usually twinkle, because they are so close to us; they appear big enough that the twinkling is not noticeable (except when the air is extremely turbulent).
Stars would not appear to twinkle if we viewed them from outer space (or from a planet/moon that didn't have an atmosphere).

Is there stars really sprinkle? Yes, just the way galaxies tinkle, and my tailor's name is Finkle. Try asking that again in a form that can be understood.

star wont really sprinckle.stars are in circle shape because sun
is also a star and it is nearer to earth compare to what stars are sun appear to be circle in shape stars as they are far away from earth they appear to be sprinckling .

No they dont.It appears to be so because of air layers in atmosphere.
