i know why starts appear to twinkel..but i simply can't understand what my text book means by planets not twinkling because they are a collection of point sources of light and their ffects are nullified...wud u b kind enough to explain what that means....

Hi. Stars have incredibly small diameters whereas planets have extended size. The 'twinkle' is caused by the beam of light from a point source being moved by cells in the atmosphere. Planets just get blurry due to this.

Saw other answers . they are incomlplete . Now the correct reason . Planets being situated closer to the earth , do not cause a twinkling effect . which arises due to refraction of light from space(rarer medium ) to atmosphere (denser medium ) . As they are closer the refraction is continuous . So the dont twinkle. For eg. Sun being a star never twinkles since it it comparitively closer to the earth (150 million km).

enable'S SUM all of it UP!!! a million. Twinkling is only led to by using the turbulent air above you. 2. while seen from area - no longer something TWINKLES. 3. because of the fact stars are "element sources" it does not take plenty turbulence to cause them to twinkle. 4. Planets are no longer "element sources" (they make certain into discs) and subsequently do no longer seem to twinkle until they're seen by using very turbulent air- esp. close to to the horizon. 5. have you ever regarded down a highway interior the warmth of a heat summer season day and seen it seem to wave returned and forth. it appears that evidently this way via turbulent warm air increasing from the concrete. that is largely an identical technique that reasons stars to look to twinkle.

well, there are two reasons. firstly, the planets reflect less amount of light whilist the energy of light is trapped by the atmosphere.the collection of point sources means the various light rays which strike the planet at the 'point distance' may meet together. their effects are nulified...????
due to refraction of light the planet appears only blurry and fuzzy.the distance also matters in such cases.
just check on some other website for better information. i may be wrong!

due to refraction of light
