Earth-bound astronomers taking Pluto's temperature have confirmed suspicions that the planet is colder than it should be. It's thought that the planet's lower temperature is the result of interactions between its icy surface and thin nitrogen atmosphere.
Using the Submillimeter Array, or SMA, a network of radio telescopes located in Hawaii, astronomers found that Pluto's average surface temperature was about 43 Kelvin (-382 degrees Fahrenheit) instead of the expected 53 Kelvin (-364 degrees Fahrenheit), which is what the temperature of Pluto's largest moon, Charon, is.
