Hi,
When sunlight enters the earth'satmosphere, it continuously goes from rarer to the denser medium and hence refraction of light takes place. The refraction of light taking place in the atmosphere is known asatmospheric refraction. ... The planets appear to be quite big to us (because they are much nearer to the earth).
Unlike stars, planets don't twinkle. Stars are so distant that they appear as pin points of light in the night sky, even when viewed through a telescope. Because all the light is coming from a single point, its path is highly susceptible to atmospheric interference (i.e. their light is easily diffracted).
