The earth's atmosphere is mostly turbulent and has a rapidly varying density. Thus light coming from any light source in the outer space suffers atmospheric refraction. The earth's atmospheric refraction thus causes the images of distant heavenly objects to appear to "swim", that is the image of the same point may seem to be formed at a slightly different point in the image space and this results in a visual effect of the temporary disappearing of the image (provided the image is too small to be recognized as a disk and is nearly a point image) namely "twinkling". The stars though much larger than the planets, are so distant that they appear like point objects in the night sky and thus their images suffer the twinkling effect. The planets though small are much nearer and can be resolved as disks even with binoculars and hence their images are too big to suffer twinkling. read less

The planet are closer to the earth as compared to the stars so the light receive from the planets must greater and the fluctuation caused in the amount of light due to the atmospheric reaction are negligble as a compared to the amount of a light receive from them so that our planets do not twinkle.

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).

they do not emit light as starts do.

The legend in education behind every high achiever

Planets do not twinkle because they are non luminescent bodies. Only luminescent celestial bodies ( stars)emit light continuously and this light when passes through the atmosphere of varying densities they seem to twinkle due to atmospheric multiple refraction.

Planets are not luminous bodies, that means they can not produce light by itself like sun or other stars. planets only reflect light which is coming from stars (Where stars are luminous ).

rs twinkle because … they’re so far away from Earth that, even through large telescopes, they appear only as pinpoints. And it’s easy for Earth’s atmosphere to disturb the pinpoint light of a star. As a star’s light pierces our atmosphere, each single stream of starlight is refracted – caused to change direction, slightly – by the various temperature and density layers in Earth’s atmosphere. You might think of it as the light traveling a zig-zag path to our eyes, instead of the straight path the light would travel if Earth didn’t have an atmosphere. Planets shine more steadily because … they’re closer to Earth and so appear not as pinpoints, but as tiny disks in our sky. You’d could see planets as disks if you looked through a telescope, while stars would remain pinpoints. The light from these little disks is also refracted by Earth’s atmosphere, as it travels toward our eyes. But – while the light from one edge of a planet’s disk might be forced to “zig” one way – light from the opposite edge of the disk might be “zagging” in an opposite way. The zigs and zags of light from a planetary disk cancel each other out, and that’s why planets appear to shine steadily. read less

Planets do not emit light as the stars do, the planet's atmosphere absorbs some amount of light and reflects the rest which makes us to see the planets and other bodies around. Moon and venus, which are visible from earth are examples. They absorb some light and reflects the rest. The stars appear to be "twinkling" because the earth atmosphere is more denser than that of the outer space and hence the atmosphere of the earth refracts the light of the stars. The stars are so far from earth as a definite position cannot be seen. So it appears to be glittering. A similar phenomenon is sky looking blue in colour, which appears to be blue because of the colour wavelength captured by human eye. But as stars are not as vast as space and also they are far beyond (nearest star except sun which doesn't twinkle, is proxima centauri which is 10x10^13 miles.. 100,000,000,000,000 miles). read less

Light waves traveling through Earth ? ?s atmosphere bend as they pass through pockets of air at different temperatures. Because the light waves come from a single point, this effect can make the star ? ?s brightness and/or position appear to change.

Planets do not emit light in contrast to stars. That is why stars twinkle but planets do not.
