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.
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.
