Answer:
Unlike stars, planets don't twinkle. Stars are so distant that they appear as pinpoints of light in the night sky, even when viewed through a telescope.

Answer:
Planets are much closer to the Earth and are seen as extended sources. So, a planet may be considered as a collection of a large number of point - sized light sources.
Although light coming from individual point - sized sources flickers but the total amount of light entering our eye from all the individual point- sized sources average out to be constant.
Thereby, planets appear equally bright and there is no twinkling of planets.
