Planet temperature & distance to the Sun

The intensity of light radiated by a light source follows an inverse square relationship with the distance it has traveled. https://en.wikipedia.org/wiki/Inverse-square_law You wonder if you could observe this trend in the temperature of the planets in our Solar System given their distance to the Sun. You'll use the planet_df dataset from the devstronomy project to investigate this.
