Us and Enceladus

Enceladus is the 6th largest moon of Saturn. It has the distinction of being the most reflective object in the solar system. The bond albedo of Enceladus is 0.81. Let’s figure out what the average temperature of Enceladus should be using the standard approach. This is determined by 2 things: Insolation Longwave Radiation from Saturn.Continue reading “Us and Enceladus”

Average Moon Day and Night Temperatures

NASA’s Moon Fact Sheet doesn’t give the diurnal temperature range for the entire moon, just the equator: Strange. They have collected the data. Why didn’t they do the calculations? So I could do it? I went through every 15 degree increment longitude data available here. Day is the center hot spot +/- 90 degrees. NightContinue reading “Average Moon Day and Night Temperatures”
