Planets do not twinkle because
they emit light of a constant intensity
their distance from the earth does not change with time
they are very far away from the earth resulting in decrease in intensity of light
they are nearer to earth and hence we receive a greater amount of light and, therefore minor variations in the intensity are not noticeable

What causes the star to twinkle?

Planets do not emit light. Actually, planets are nearer to us. That is why, we can considered it as a collection of large point size objects.

The dimming effect produced by some of the point source of light in one part of the planet is nullified by the brighter effect produced by the same. So, overall the brightness of the planet remains constant. That is why the planet.

Planets don't have their own light. There light is minimized by different source of light. That's why planet do not twinkle.

Planets do not twinkle because they cannot emit their own light we say that Venus is morning star because it is near to sun.

Because planets have no self lights. It brights with the light of sun. Because all the planets are depends on sun lights so no any planets looks from the earth.

I think planets just reflect light falling on them but we can see that sometimes we can see the mars planet when it has come nearer to earth atm.

Meaningless options are there remember one thing that planets never twinkle they only take light of sun to looking like twinkle just like venus its simple way to understand you.

Planets have no light. It just reflect light. Move Over, the Planets are closer to us. Stars have some tiny dust particulars so that it looks like twinkle. Stars are more far away from us.

I am not agree with above all answers. The basic difference between stars and planets is. A star has its own light (Our SUN also one of the star). But a planet has no light of its own. It shines by reflecting the light of the sun.

The planet is nearer to the earth. So the intensity of light is more provide. So the planet do not usally twinkling.
