Aplanet's temperature depends on its distance from the sun as well as the strength of its greenhouse effect. let's remove the effect of distance from the sun by just considering how the temperature of a planet changes due to the presence of its atmosphere. calculate the difference in temperature for each planet with and without its atmosphere, and then rank the planets in order of increasing greenhouse effect.

earth, venus, mars
