Planet Distance Parameter
   The planet's distance from the star affects how much solar energy reaches the planet. As the distance increases, the sunlight becomes "fainter" and there is less energy to reflect and absorb. The reduced reflection will cause the "reflected sunlight" peak in the spectrum to become smaller. The reduced absorption will lead to a lower surface temperature for the planet and will result in the infrared peak becoming smaller AND moving to longer wavelengths (in accordance with Wein's Law).
   In the "Visible Appearance" display, increasing the planet distance will move the planet farther out from the star AND make the planet "fainter" (since there is less energy being reflected).
