Examine the chart below of the average mean temperature (°C) of each planet in our solar system.

Generally, what happens to the average mean temperature of the planet as the distance from the sun increases?  Why do you think that occurs?

What other factors could contribute to the average mean temperature of a planet?

Which data point is an outlier? (An outlier is a data point that is much bigger or smaller than most of the other data points in a set). Why? What do you think accounts for this difference?
