Fun Fact Friday, Number Twenty-Seven!

Today’s fact is under the category of astronomy.  Do you know which planet in our solar system has the highest mean surface temperature?

If you guessed “Mercury” (based solely on the fact that it is the planet closest to our sun), you would have guessed incorrectly.  The planet with the highest mean surface temperature is actually Venus, whose gases (mostly carbon dioxide) actually trap the heat making its surface hotter than Mercury.  Who knew?
