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.

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

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 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.

What causes the star to twinkle?

Does our star, i.e.; sun twinkles? off course it does not appear to be. That's because it is very near to earth relative to other stars and hence a greater amount of light reached does not allow varying intensity so it does not twinkle. So far as I think logically, there is a close relation of twinkling with distance and thereby varying intensity. Tell me if I'm wrong. :-).

Planets don't twinkle (so much) because unlike distant stars, they are not "point sources" of light. A star is like a single pixel, and the atmosphere can distort the light of that pixel easily.
A planet is like 100's or even more pixels, so the distortion of a few of those pixels is too slight to notice. Sirius is brighter than most planets, and yet twinkles. So the "more light" explanation doesn't hold up.

Stars 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. Thus the stars twinkle. That is to say that planet do not twinkle, because they are nearer to earth.

The planets are much closer to the earth and are seen as extended sources. If we consider a planet as a collection of a large number of point sized sources of light, the total variation in the amount of light entering our eye from all the individual point sources will average out to zero. Thus nullifying the twinkling effect.

Planet has not own light yet sunlight reflecting by them so they shine.
