3. It has 'cleared the neighborhood' around its orbit

Pluto has not 'cleared its neighborhood'

if the earth's atmosphere were 50times denser than it is, would sunlight still be while or would it be some other colour? explai
katrin2010 [14]
If the atmosphere were 50% more dense, sunlight would be much redder then it is now. As the atmosphere increase in density, more and more of the blue light would be scattered away in all directions, making the light that reaches the ground very red. Think of the color of a deep red sunset, but this would be the color even at noon.
Hope this helps!
