Distance from the sun, planet’s size, atmosphere composition
Atmospheric pressure, distance from the sun, albedo
Solar flux, planet’s reflectivity, greenhouse effect (correct)
Atmospheric composition, distance from the sun, solar radiation

What does Wien’s Law describe?

The amount of energy that passes through a given area per unit time
The flux of radiation reaching its peak at a wavelength inversely dependent on the blackbody’s absolute temperature (correct)
The relationship between a planet’s distance from the sun and its average surface temperature
